Most of his supporters think he is reasonable about Islamic terrorism, and this his responses to them are justified. It's probably one of the main reasons they voted for him.
Allow me to correct myself: I don't think anyone
in this conversation thinks he's reasonable about Islamic terrorism.
I don't see this as a separate subject just because of the race or ideology of the attacker.
It's completely irrelevant what
you do or don't see as separate subjects, unless your point is that you wouldn't make the statements Trump made if you were in his position (lol no shit).
To remain internally consistent (not right, just not self-contradictory), you'd have to propose that it is impossible for a person to view the two as separate subjects. I propose that it is possible, and that Trump is likely to perceive it so.
