"Why add more fuel to their fire. "
Laura, honestly I was trying to find an understanding. Your vote seems to really worry a lot of people - I think it's because for the most part people respect your opinion.
If you really think trump was as good a choice as Clinton, or it was close enough not to be a big deal either way, then voting 3rd party in a swing state would be logically sound. Heck, if you thought trump was better, then voting for him was logically sound. If that's how you feel (and I seem to remember comments about him really being a liberal), then that takes us to a different, but more typical right-left argument.
But if you see both trump and Clinton as bad, but recognize that trump is significantly worse, then voting 3rd party in a swing state simply doesn't make numerical sense; you aren't doing what you can to get what you most want. If you know that, but still don't vote for Clinton because of some emotional hang up, then that's strange and incongruous.
It's all fine to blame the Democratic Party for running Clinton, but when it came to voting day, in an effective two party system one has to make a call.
I think we could put this to rest if you came out and clearly said you didn't care if Clinton or trump won, ie all the crap that trump has done and will do is equally bad as the (different) crap that Clinton would have done - you'd probably be challenged for that, but we could at least let this 3rd party voting logic issue pass.
