Wow. This is a lot to unpack from a short convo. 1. I think you made a fair point. Even if it isn't the most NSFW content on here, and it isn't, if you felt uncomfortable of thought others might feel uncomfortabe, you have a right to say that. 2. You are being very mature and reasonable. You did NOT tell them to delete it, you did NOT call their art trash, and you did NOT cuss them out. 3. They were very rude. They told you to fu*k off, just because you were voicing your opinion. They yelled at you to leave for saying what you think. I don't think it matters whether it should have been 18+ or not, what matters is how they acted.
