He's.... basically playing up his support for the white supremacist/neo-nazi rally that ended in a terrorist attack killing an american citizen, he's doing it by trying to bothsides at a side that just kinda' isn't there.
I'd just like to interject that Fields hasn't been charged with terrorism, and I sort of feel it's jumping the gun to say it was a terrorist attack. The guy's a diagnosed schizophrenic, and until his trial he isn't going to get any chance to defend himself.
I'm not trying to make excuses for the guy; I personally feel he's a murderous asshat. But, until there's been an investigation and a trial, nobody'll know for sure what actually happened.
Edit: I'd like to clarify more, since I reread this and felt I wasn't clear enough: my point is that labeling this an act of terrorism without proper investigation feeds both sides. No, I'm not pulling a whataboutism, it's just fact that both political extremes will use this, and are using this, to their advantage. The far left is using it to pull down confederate statues and gain support, while the right is using it to claim victimhood.
Again, if you're on one of those sides, you may see that boost as a good thing, but I fear it'll lead to more violence.
