Yes. You said it was a joke and then also took something as a personal attack that wasn't.
I have no interest in reading long rambling comments from someone that makes the topic about some personal insults they inferred.
Inherent bias of race or religion is not an attack on you personally. It's not a flaw of your personal morality. It's something that is a part of our society that we should all be aware of when analyzing "groups".
Instead of having that conversation you instead made it about some personal moral failing. Which, is just fucking boring and not worth my time to read or refute. I don't care about whether or not you think you're rascist or not. The thought never crossed my mind.
