There are so many things to be concerned about in the world
That’s exactly it. Present day conservatives don’t have any solutions to current problems, so they have to make up a boogieman that has to take the blame for all that is wrong in the world (instead of the actual causes) and that only they can save their followers from (because everyone else is already “indoctrinated”.) Anything that’s against “traditions” is a good target (often a minority that’s starting to get treated in a more equal way.)
The CxU (among others) is working on making those clowns a viable coalition partner by taking them seriously and talking to them on TV. Maybe that’s not their intention, but it will be the result if it continues.
