I think that anyone who plots to kill, attacks, or harasses normal people of all kinds is an @sshole.
They may be Trump supporters, but this sentiment very much predates the Trump presidency. I don't think Trump is their reason, but is being used as a convenient excuse. Not by these jerks, but by those who want to tarnish Trump's name to suit their own political agenda.
I'm not Muslim, but I am Jewish. Meaning, I'm part of the group that, statistically speaking, is more likely to experience religiously-based hatred in this nation. Yes, more so than Muslims, believe it or not. Trust me when I say that these kinds of people existed before Trump entered the political ring and that their hatred was stewing long before he campaigned. It really helps no one by trying to say that Trump is encouraging them, consciously or not, because honestly that very well may not be the case.
