Like I've said, DS9 is my least rewarched, but I recall Sisko yelling in anger quite a bit. Shaking. Seething. Also being "loud" very often... excited to greet someone, laughing loud enough to startle passersby, that kind of thing.
Basically, a stereotypically loud black guy.
Compared to Kirk, Picard and Riker, Sisko was loud and angry, by magnitudes.
I think people who haven't grown up being told not to be an angry, loud brown dude don't see it.
You saw that as a humanazing trait, I saw it as another portrayal of angry black man. Had he been white, it would've read differently, but in the cultural context of when it was created, when angry black man was ubiquitous, it plays into the sterotype, whether intentionally or not. Again, being blind to it is as racist as doing it on purpose.
Race blindness, while supposedly an ideal goal, is also a type of racism, in a world where racial and cultural differences, racism and stereotypes exist. It's a universal "well meaning" form of prejudice I daresay most people are guilty of.
First of all, thanks for sharing all you said in your posts, much appreciated. I believe I get where you're coming from, and it makes me think. And while I (being a white European) am not really qualified to judge what good(!) Black representation is, I want to share my thoughts on Sisko--as I perceive him.
First of all I want to address the matter if he actually is that angry. He does express his anger more so than Kirk and Picard did, but I don't think that's an entirely fair comparison because Sisko is in a setting that's inherently much more conflict-laden. Kirk/Picard commandeer space ships where everyone is in Starfleet and works together, and even when meeting other species/cultures, they have an obligation to be diplomatic. Picard is even often criticised for being too emotionally repressed.
So I think Sisko showing more anger is at least partially inherent to the different kind of show that DS9 is. Besides, I think the angriest person on DS9 is Kira, at least early on. Sisko is... eccentric... in his display of anger, but I believe that's Avery Brooks being Avery Brooks more than a writer's or director's choice.
I can see how his depiction may remind of the terrible stereotype of Black people being angry by default. The difference being, as others have pointed out, that I see his anger as justified and I'm 100% with him, as opposed to the stereotype that depicts Black people as being unreasonably angry or even dangerous. Not saying I know better, just how I read it.
This raises questions about how to best avoid bad tropes and stereotypes. While it's obviously good to be aware and avoid them, the question is at what point do you try to avoid them so much that you stop writing characters? As in, is it better if you end up having only calm, friendly, inoffensive characters like Uhura and Geordi? Because then I'm afraid that we're in turn recreating the racism of white people being allowed to be angry and Black people being not. I guess you could say, try to keep it below a certain level, but I think that's still putting constraints on Black characters but not white ones.
The way I felt about it is that Sisko is
allowed to be angry, in a way that's actually breaking through those constraints, depending on how you look at it. The usual stereotype tries to tell me that Black people are angry because that's just how they are and you shouldn't listen to them. Sisko seems to tell me that yeah, this Black man is angry, but listen to him because he's
right! And doing so, in a way I think it's actually fighting the stereotype.
I believe DS9 is also the first time one actual Black perspective finds its way into Star Trek. Classic Trek is for the most part well-meaning and liberal, depicting a colourblind utopia where we fixed racism etc. And while it certainly brought some advances (well, at least TOS did), even if there's some diversity it's always told through the perspective of white people. Showing characters how white writers see them, telling stories that matter to white writers.
Avery Brooks changed that because he threw in all his weight and had a lot of input on Sisko. He insisted on being depicted as a loving, caring father because fighting the deadbeat dad trope mattered a lot to him. He was extremely invested in Far Beyond the Stars (even directing it) because it mattered so much to him. Sisko has an issue with the Vic Fontaine fantasy where "everyone" is having a jolly good time in 60s Vegas, presumably because Avery Brooks had an issue with these 60s nostalgia fantasies. Not going into if it's resolved well or not, but that it even comes up shows that this isn't made by white people only.
As for the being American thing, I didn't know that this was also due to Brooks's influence, but that doesn't surprise me at all. If you look at the other Classic Trek shows (by which I mean, up to and including ENT), not a single Black regular is canonically from America, despite all the actors being American. In the case of Uhura and Geordi, I guess it's commendable that they wanted to include canonically African characters, although questions arise about how this TV show made by white Americans puts all Black characters in "foreign" roles.
TNG's other Black regular, Worf, is an alien. Recurring character Guinan is an alien. VOY's only Black regular is an alien. Two of ENT's lead characters are white Americans, the Black regular isn't even from Earth. Avery Brooks couldn't have known about the latter two shows when his character was created, but there's a pattern that may have made him say "screw that, I'm from America. From the south."
All of this is not to say that everything's perfect, or that I'm right, again I'm not qualified to judge that. But I hope I could explain my thoughts why I perceived Sisko as mostly good, and an actual advance over the previous (well, and following) series.
