If you're afraid that Arabs will react violently to the Jerusalem capital recognition, then you've just proven why the travel ban is necessary.
Are you saying all Arab people are violent?
I'm suggesting that arabs are dangerous people and should be banned from entering the U.S. Thus, the travel ban.
You shouldn't assume all Arabic people are dangerous. It's not okay to judge an entire group of people based on the behavior of some. All that does is play into stereotypes and stigma.
