How exactly do white people make for better disguises,
Because of the racism they will encounter, conscious or otherwise. If I were an alien plotting to destroy Earth and thinking about the best way to evade any whiff of suspicion, I'd opt for a good-looking young white female skin. Lisa's skin is just about perfect (although maybe she should eat a few burgers or guinea pigs).
and what does Ryan's attractiveness have to do with anything, outside of the obvious, his sex appeal?
Because both men and women like to be around attractive people, regardless of romantic possibilities. And why discount sex appeal? Imagine if Ryan's boss were a smitten female executive. As a V spy, that would come in very handy. A V spy who looks like Ryan will be much more effective than one who looks like Woody Allen.
And why would Ryan's looks and job attract liberal white guilt type friends.
Because my observations of people are that white liberal guilt is much more common than people acknowledge or are even aware of, in themselves. Aliens observing our culture from the outside would be very good at picking up on things like that and the best way to manipulate people is to use things against them that they aren't even aware they possess.
Putting a handsome black man in a professional setting allows a different set of manipulations than putting a handsome white man, or women, in the same setting. It would be smart of the V's to try everything. Maybe there's someone powerful in the company where Ryan worked that was more manipulable by Ryan, and a different person who would respond better to a different type skin. The V's would try various options and then go with what worked best.
Are you implying that some professional blacks arouse guilt from some liberal minded professional whites? And that these people befriend them out of that?
Yep. I'm 100% certain that goes on, so why wouldn't the V's see that and exploit it?
But that's just the tip of the iceberg. There are a myriad of ways the V's can exploit humans via various neuroses and prejudices. I didn't mention that it's well established that tall people do better in business and other life situations than shorter people. Therefore, the V's would also opt for taller than average skins. That wouldn't preclude them using shorter stature or even dwarfism if they found situations in which those attributes gave them an edge.
Practically, I think the Vs are overwhelmingly white because the writers, the executives, and the advertisers that spend money on the show are probably overwhelmingly white just like for many other TV shows, and their fictional worlds perhaps reflect their real lives where minorities are not significant parts of it.
Well, yeah, and the V's are all pretty because actors are pretty, and I'm probably grossly exaggerating how much thought the writers put into these things, but it's more fun to come up with in-show explanations for these things.
Here's the real reason Ryan is black: because every show needs its token black major character. But he's never the lead character. I guess
V is being kinda groundbreaking in having a female lead character, and making the black guy a more unique character than just the sidekick, badass or priest.
And to be fair to V, Morena Baccarin is from Brazil. Not sure what her ethnic makeup is, but she doesn't look 'white'
She looks plenty white to me. She could be Italian or even Irish.
