Re: it's not the Catholics that are the problem. It's extremist protestants.
Sure, but by the same token the problem isn't "Muslims", it's a small subset of "batshit crazy whacko Muslims."
The issue here is that in both cases - Muslims and Protestants - there exist at the present time a bunch of really hard-core extremist beliefs being espoused by charismatic leaders and forming their own organized micro religions. At the present time they are the biggest threat.
I am perfectly aware that the majority of Protestants are completely loony tunes (disregarding the who "they believe in a sky fairy" part for the moment; that's actually somewhat normal, sadly.) I am equally aware that the majority of Muslims are not blood thirsty whack jobs.
For now, however, the extremist elements of both collections of micro-religions are attracting a disproportionate amount of crazies and causing disproportionate amounts of harm.
