Well, I actually used to be more leftist before, but at some point my values changed, it seems. I do not see how my social position is relevant to the discussion.
Unless you are here arguing against your own interests (and I’m choosing my word there carefully) I’d say it’s pretty relevant.
I think you would say I was arguing against my interest when I held socialist(like radical socialist) beliefs. My values changed since then. We are not defined by the circumstances we find ourselves in.
Also, I reject that class war rhetoric that is championed by Marxists.
In any case, I am arguing in good faith. If my social position is enough to make you disregard me completely, then you are not.
