Unfortunately, they feel they have found like minded people within the conservative movement.  Whether they have or not isn't relevant, they believe that conservatives think the same way they do, and that should give you reason to look at the message that conservatives push.  You are trying to use the "No True Scotsman" argument, but unfortunately, that is just one more logical fallacy that is used to try and distance the right from these groups. 

 I am NOT saying that conservatives are haters, but if the haters believe that you think like they do, I might examine the rhetoric that the right tends to use.  It is very much the rhetoric of division, of demonizing whole groups of people, whether it is Trump and his "Mexican Rapists" line, or the more subtle rhetoric of calling Obama boy, both are pushing an idea of minorities are somehow less.
