You should at least
try to describe it more specifically if you're casting shade on a huge population. Otherwise you just look like a bigot assigning traits to tens of millions of people based on a few people with the same religion that you know. I grew up Mormon and I've also lived and worked among mostly non Mormon populations, and I would say most Mormons are actually not militant.
Turns out Mormons are just people too with a huge diversity of personality.
