And my point is that this is a biased assumption, and that even in media where everyone is white and straight, there are tons of characters that aren't all that special, mostly because they're not relevant enough to the story to get the neccessary screentime to develop as more than "random person walking by". However, having all random people walking by being white and straight sends a clear message to white straight people that the world is all about them, and a message to anyone else that they are simply not welcome. Anywhere. Period.
Which is pretty much the same message that being killed in the streets sends us!
Sometimes there is a character that only exists to deliver a message to the mc. If that character is white, people will think "oh it's a random character who exists only to deliver this message". If the character is black, it's suddenly "oh it's just a random person-of-color character that the creator threw in to be politically correct". How about no? Maybe it's still just a character who's there to deliver a message, only they happen to be black? I am sorry but I find this attitude of "black/trans/gay characters are not allowed to exist in the story unless they have a good reason to be there and a good reason to be black/trans/gay" attitude to be rather bigoted, for lack of a kinder word. What this translates to for a real life scenario is "black/gay/trans people are not welcome unless they prove themselves worthy by my standards and unless they give me a good reason why they're the way they are". Basically for some reason everyone has to adapt to suit a white man's wishes and world view. Why?
I'm sorry but your understanding of this situation is very out of sync with reality.
Speaking as a trans gay dude who was bullied into the closet and self denial by people like yourself, I'm sorry to say we are the ones who have bent (just a kind little grammar correction for you to keep in mind next time) over backwards long enough for the wishes of the white, straight and cis. And we still have to do it. But we are finally pushing back, and that makes you feel like you are bending over backwards because you're forced to return to a fair position from the overstep of boundaries you have done. And yes, I do say "you" because in this case the attitudes that you have displayed on these forums indicate that you are very much part of the problem. If this is something you don't want to be called out on, then you can easily stop being part of the problem by becoming more respectful, accepting and openminded.
This is a misconception of what "feminist" actually means. You might find a bunch of very loud feminists claiming this, but they are radical feminists. Most feminists just want equality, and claiming that every man ever is sexist is not a good thing to do in the spirit of equality. That's just another form of sexism.
I also feel like I should point out that you're trying to bite back at me using the mannerisms of radical feminists as an argument, when many of said radical feminists are very trans exclusionary. No, really. They hate us and they think we are poisoning feminism.
We only want equality and the ability to live our lives without fearing that someone will murder us just because of the way we were born. Please don't confuse us with people that are sexist against men or who straight up exclude us from their movement.
If you don't want to sound like you have a grandiose ego, this is probably a manner of speaking that you should avoid.
Another thing you should probably avoid is talking down to, and being disrespectful to, people who could have been beneficial to you on a platform that is beneficial to you. You have a webcomic you've been trying to grow, and a lot of times having some friendly connections with other creators, whether small or large, is helpful both for personal growth as a creator, motivating support in hard times and even for cross-promotional purposes. Now I'm not saying you and I would ever have been able to get along in this way, because we probably wouldn't, but the thing that is happening with the way you behave is that you are giving yourself a very bad reputation and scaring away other potential future friends in the webcomic industry. Disagreeing is fine, but the least you can do is try to be polite about it.
Another thing you should probably keep in mind is that what is stated online, stays online. I can't erase my past shitty behavior, even now that I have matured far past it and hate my old self and the things I wrote. I have a feeling you will mature a bit with the years, and eventually regret saying all these things. The more hate you spit, the more you'll have to regret. Just a few words of advice from someone who used to get way too heated and douchey in discussions himself.
