Maybe i'm just naïve and blind, but I honestly don't think that's as often the case as we may be conditioned to think.
"Conditioned?" Hate to tell you this, but no one "conditioned" me to think anything except my own observations.
I think we need to take a more holistic look at how we view people and their opinions, especially when their way of expressing their feelings is a little "immature / passionate," and not immediately jump to "obviously these people are racist homophobe white supremecist assholes..." because historical evidence doesn't support that intense hatred for franchise products requires that element.
I feel like we're conditioned to see racists and bigots everywhere. Respectfully, we need to be better than that, and we need to be more thoughtful. I generally try to stay out of discussions about cultural / political stuff here, because I come here to escape, not engage in that stuff. But...I feel I need to gently and respectfully say my opinion here.
Don't let a few loud jackasses online and on YouTube lead you to believe that people who react strongly to something they are passionate about are driven by bigotry. There surely are some, but I don't think it's the numbers some of you are thinking.... Some of those "haters" may be annoying, grating, insufferable assholes....but that doesn't make them bigots.
I don't disagree with you that there are people who hate something, even unfairly, without being bigots. But I've been in online fandom for over twenty years. I can suss out the difference. If someone is upset or outraged that characters like Burnham do literally all the same things every other captain has done, that tells me this is not just about the quality of the writing.
