It's crass, tasteless and more than a little rich to try to bring down Clinton by pointing out that one mass shooter supported her, especially when there's nothing Clinton has proposed that would encourage his actions. Here's the thing: Trump has attracted legions of white supremacists (including key KKK figures) and anti-Muslim bigots (the kind that beat up Muslims in the street) because of his platform. Right now, the Clinton link is merely coincidental at best; the Trump link is undeniable.
It's going to be fun when Trump loses and you spend the next 4-8 years writhing in agony as empathy, tolerance and civil rights rule the day.
