Yes, you’re rage-baiting; a republican candidate would have been labeled that way because of the aggregate of their positions, not this one.
Though of course, that is by modern standards quite a conservative right position to take. (And incidentally not one I’d consider reasonable to take; though I’m obviously biased by being directly affected)
No, I don't think it takes more than one position to get you labelled "far right" these days. The Free Speech Union, which is UK pressure group in favour of free speech was recently labelled "far right" by Wikipedia for promoting free speech.
I just checked the wiki, but can't find the far-right references.
There is some chatter in the Talk page about some members of the group associating with far-right figures and pushing some very dodgy views on far-right topics. Is this what you are referring to?
