My whole opinion over this rcdart debacle is that people are free to draw what they like. No one has the right to stop them from drawing. Freedom of speech and expression (the concepts, not what they produce) needs to be respected, even for things one considers distasteful.
That being said, you can also express your distaste. That’s how freedom of speech works! As long as you are appropriate about it. Death threats and suicide baiting are 100% inappropriate. No one deserves to die because they draw art you don’t like.
I personally find the art disgusting and transphobic. And if they were honest about their fetish, I would be a lot less critical. The biggest issue is them disguising their fetish as inclusivity and activism. There are too many red flags for it to be the product of just stylization, and I feel like it needs to absolutely be addressed.
But they don’t deserve to die because I think it’s gross and fetishistic. Criticism is fine as long as it remains criticism and doesn’t enter the realm of being threatening. And if you mock it, you’re free to do so too. Art is not above mockery. I make fun of contemporary abstract art all the time. I make fun of generic tumblr stylization (we all know the one) all the time. If people can’t handle that then I don’t know how they’ve gotten this far as an artist.
But in no way are they obligated to appease you or remove their work. Say what you need to say, hope that maybe they’ll learn and change, and if they don’t then you block them.
