the person you're replying to is notorious for constructing ethical frameworks out of thin air then using loaded language and blame/shame tactics to high road any interlocutors who disagrees or adds nuance. theyre actually pretty good at boxing people into corners by steel manning exaggerated versions of their position then knocking them down with pearl clutching tactics. something along the lines of, "I can't believe you laughed a joke about! Don't you know laughing or thinking about a bad thing is morally equivalent to doing the actual thing?!"
they're otherwise actually pretty based in their views and make valid points but come off as antagonistic and self-serious to the point of discouraging others from engaging in conversation where people are allowed to grow and evolve their opinions.
best to tag and move on.
