I think he is a shallow, ignorant and dangerous idiot who doesn't put his small brain into gear before mouthing off.  I suspect that his recent stupid remarks will incite more attacks in the US resulting in the deaths of ordinary citizens.  He has probably made himself a prime target too although I have no sympathy for that.

And how, hypothetically, if he could exclude muslims from entering the US, would he go about it?  Is every tourist or visitor on business to be asked what religion they are on entry, and how would they prove their honesty or not?  Stupid brainless man who thinks he is important just because he is a billionaire and can pay for his own campaign.

Already there are almost 200,000 signatures to a petition to ban him from entering the UK. I doubt it will make any difference but at least it will have to be discussed in parliament.  I'd like to think he could be stopped from visiting his environmentally damaging golf courses.  Failing that dump him in the middle of Birmingham or the parts of London he claims our police are afraid to go.
