"Rightist" sounds off, but I'm comfortable calling a majority of the content of the politics stream "right-wing." I mean, it clearly is.
"Leftist" is intended as an insult but I don't really care. I just think it's funny as applied to me and indicative of the site's right-wing tendencies.
--I support basic things like taxation, welfare, environmental protections (including greenhouse gases), etc. I oppose racism, sexism, homophobia, and other bigotry at a basic level
--I don't support seizing the means of production, cancelling all student debt, or blaming straight white men for every problem in history
--I oppose Trump because he's a constitutional oath-breaking moron and myriad other reasons I'm not going into right now. I voted McCain in '08 and Johnson in '12 and '16. I've never voted for a Democrat to be president. But it's going to happen this time because Trump is an idiot who has turned the GOP into a hot mess and the Libertarian Party is going nowhere fast. Have these parties pushed me farther to the "Left"? Sure.
McCain and Romney: presidential nominees in '08 and '12, now both considered traitors. The GOP has changed fast.
