No, it's not inflammatory. You don't have to agree with it or condone the idea of a blanket ban on Muslims --- you don't even have to stop supporting Trump to believe we shouldn't ban Muslims.

What you can't do is object to facts that are simply on the record. Trump said early in the election cycle that he supported a ban on Muslims, and then after the election Rudolph Giuliani looked straight into a TV news camera and said that the travel ban was an effort to put that kind of ban into practice.

There's easy inflammatory versions of this observation. For instance: someone could accuse you of supporting bans on Muslims for debating the substance of the travel ban. But that's not what 'mikeash wrote, and it's not fair for you to take him to task for that.
