Not saying you should assume or stereotype, but let's be honest here: One of those 3 is the majority of the religions mentioned and most outspoken in this country with their anti-LGBT views...to the degree where we have politicians who affiliate with said religion and espouse said views.I wouldn't assume. Most likely Islam, Judaism or Christianity.
But that really is a topic for another conversation. Point being this movement (which I once supported mind you) is potentially turning into something really ugly and becoming the very thing they're protesting against.
