why not religionism ?

[BrianSoddingBoru4]

But IS there a recognized term for discrimination against religion? ‘Religion discrimination’ is kind of clumsy, and (as has been pointed out) ‘xenophobia’ is just too broad.

Let's put it this way, is atheism the irrational prejudice against atheists?  I think the term has more potential for confusion as it's not at all clear whether it's pro or con.

Maybe that's just unfamiliarity, I don't know.

Fair point. But there are also plenty of 'isms' that indicate prejudice - racism, sexism, ageism, ableism, and so on. But no one thinks 'racism' means anything other than a person who discriminates on the basis of race.
