Have you watched his Oxford Union speech? TR is a criminal thug and a rabble-rouser. But the case he made could have been made by any intelligent secular liberal, and it wasn't anything like being rebutted.
"Immigrants are the devil" is a stupid argument. What is not though is: "Islam is an unreformed religion that in its scripture, in the beliefs of most of its adherents, and in how it is practiced by many Muslim states is deeply illiberal, as evidenced by attitudes to and treatment of homosexuals, sex outside marriage, child marriage, treatment of prisoners of war, and ethnic (/religious) cleansing, and it is entirely reasonable to be 'suspicious' of it as such".
My personal view is it's not fair to be any more 'suspicious' of Islam than we would be of, say, medieval European Christianity (or many other non-religious belief systems at other times). And that it was perfectly rational to be very suspicious of those. If we thought that was bad then, we should think this is bad now.
None of that means believing that all, or even most, medieval Christians were 'the devil', nor does it deny the many very admirable traits and works of that religion (ditto Islam).
