I have answered your argument. The only person “trying to evade” here is you.

You keep talking about lefts and rights, while I'm saying I don't see any difference of substance between class, race, and sexuality insofar as it regards to politics.

At best you're misunderstanding, at worst you're disingenuous, and either way you aren't carrying your half of the conversation.

I’m talking about “left” because how to define that term is the topic of conversation. And I don’t see how could can define “left” without defining “right” - the two terms have always existed as a pair.
