You said he thinks that voting for democrats is accelerationist, and he explained why he believes that.
You claimed that he thinks all of leftist thought is whatever tankies think (a pretty vague claim, tankie is not exactly a well established term), and then you use some flowery sequence of platitudes without real refutable specifics to propose a broader definition of leftism. Cowbee responds by clarifying what he believes leftism is, which is broader than his own ideology.
What words are you saying he ignored? Are you upset he didn't answer "how ya been?" Are you confused as to which comment he's responding to?
