You are just wrong. My non vote for Hillary is not approval of white nationalism.
No we're past this now. Sorry. We had primaries, and things were up in the air, and while it looked like it was coming down to what it is now we couldn't be sure, and even if Trump won there was still some question as to how he'd run a general campaign, and everyone was understandably voting for their personal preference.
It's Clinton vs. Trump. No one else is going to be President. Trump has, like, quadrupled down on everything in the primaries. It's Clinton vs. a white nationalist. Not voting for Clinton is not technically
approving of white nationalism but it
is readily accepting the consequences of a white nationalist President, which is a distinction without a difference. Especially if you're not white.
