Their first paragraph was about how you said some things based on only reading a few words about them or something, like the whole liberal/neoliberal conversation hasn't been going on for a while.

And then their second paragraph was saying they are going to block you because they know you'll be condescending, judgemental, and insulting.

I just wonder how we got to this point where so many people have so little resilience against what others say while disagreeing with them, even if it gets insulting. And while I don't think anyone is obligated to engage with someone being like that, I've always seen block functions as a tool to deal with ongoing harassment not one-time disagreement (or in this case, the potential for disagreement).
