I don't see anything in there that even mentions Harris making a claim about Muslims being expelled from the US.
Have I missed it?
His claims about the ideas of Islam are an opinion. The truth of that opinion is quite subjective.
It's not bigoted to say that a religion holds a lot of bad ideas, though. What's bigoted about that statement?
You can analyse the tenets of a faith and hold them up to scrutiny. I don't see a problem with that.
All ideas should be open to criticism.
Religion is the root of all evil. And has been for centuries.
