This is absolutely stupid. Islam is not a race of people, and it's not a geographic area.

Islam is a religion, and any one from any race can join said religion.

We're not mad about "Arab extremism" or "North African extremism", because the place a person is from has no real effect on whether or not they'll be radicalized. However, their religious ideals can and do seriously affect those chances.

Your joke isn't funny because you're completely missing the point; Trump, as much as I hate the guy, isn't trying to ban Arabs. He's trying to ban Muslims. Which, while I still think that's almost as stupid as the drivel you spout, is a significant difference, and your Herculean efforts to make a point (and failing), only look even more pointless in this context.
