When a muslim coworker donates $1000 to support overturning marriage equality, yes, I would absolutely tell them that's fucked up and if they were in a C level position I would voice an opinion that they do not uphold our company's explicit core value to be inclusive.

I absolutely do not give a fuck about what someone PRIVATELY believes. The problem is not religious people believing in something, the problem is religious people FORCING their beliefs into law.

When muslim people do that, it's called Sharia law and I am against that, same as I am against laws based on christian beliefs.
