If your response to an argument is inb4, you don't get to tell somebody else they're not putting in enough effort to provide substance. Also, I brought up race dynamics before your inb4, so even if anticipation counted as more than a shallow dismissal, you didn't meet that bar.
I really don't understand what's happening here lately such that 15-year-old accounts are behaving so poorly. This is the first time you've said 'inb4' in what I can only guess is thousands of comments over a decade and a half. If you don't care about the standards here anymore, why stick around and make things worse for the rest of us? Is there some other draw than quality of conversation?
I wrote something earlier to the same effect and wound up deleting it because it let too much frustration through. I am frustrated, but you don't deserve the brunt of that. Sorry if that's still coming through.
