If you think the nutjob wing of the GOP is limited to just Trump you need to read more. Almost all of the frontrunners this cycle (outside Rubio) and all of them last cycle outside Mitt are off the reservation wackos. Seriously look into them, see what they stand for and the things they say...
Trump is just the loudest and media savviest. Ben Carson and Cruz believe most of the same crap and Fiorina is just hopeless and incompetent. Not ony are they social nutbars they arent even fiscally conservative.
You disagree with BLM (btw so do I for various reasons) so you try and equate them but there is no equating. Wanting cops held accountable for the deaths of black people =/ hating an entire religion, sexual orientation...etc. They are not the same, the GOP has gone full loony. The decent ones are drowned out by the noise and the money.
