You: Insult a group of people that had no power over their condition
Them: Insults no one, has a ridiculous username
Your reaction: You’re disgusting! I’ll block you!
Calling a username disgusting is not the same as calling a person disgusting. I even wrote “nothing personal”.
That’s not what they mean, they mean that the person had a valid point and just had a clearly silly and exaggerated name but you decide to engage with that rather than their response to your question.
