100% facts!!it's easy to not understand why people are so fired up about if one has never grown up and not seeing heroic characters that look like you doing badass stuff. Seeing people that look like you being non-existent sucks, but being the sidekick, the joke, the punching bag, vilified, or some stereotype sucks worse.
So when you have a character who was literally created at the height of civil unrest and was created to dissolve the stereotypes around black people and show that they can be just as heroic and special as their white counterparts, and said character has such historical and social relevance, being cast aside like garbage, and the people doing it are saying isht like "is just a mantle, he's just one in a long line (which originally he wasn't, he was the first) and hey look we have these black stand-ins" it affects people.
Representation matters. And its people who are always represented that come in and ask what the big deal is are the ones who don't understand it because they have never not been represented.
Not necessarily saying that your one of those people but just food for thought.
