I suspect it’s far less common, but I don’t have any numbers.
It depends in large part how you define “atheist”- does this include people with religious or spiritual beliefs, but don’t believe in a diety?
Or does it exclude the supernatural altogether?
Regardless, personally… I don’t care. Like, yes, absolutely equal rights to love who you want. Absolutely should be codified into law. Don’t get me wrong… everyone should have that right… and equal access to healthcare, and the rights to decide what happens to and in one’s body.
But personally… I don’t care. I don’t care if you specifically are gay, or if you’ve had six abortions in the last year. It just doesn’t matter- and it really, really Shouldn’t matter at all.
That people are trying to make it matter… trying to discriminate and make it illegal? Yes. That matters. That’s wrong and evil. Their hatred is something that we need to stand against.
