Religion has been a protected class for the longest time.

I don't understand how that's relevant. The comment I replied to was arguing about applying the same standards in free speech, whereas "protected class" refers to employment discrimination.

Religion is not a personal choice? Is your philosophical stance a personal choice?

Yes, it is. My philosophical stance has been changing and evolving constantly over these 40+ years that I have been alive. Unlike my race or my sexuality, it's not part of who I am, it's part of who I choose to be.

In fact, I would go so far as to say that anyone who feels like they have no control over their religion -- the same way they have no control over which color of skin they were born with -- should seek help because they're being abused by someone.

But bringing up your sexuality in the workplace is a personal choice.

"So you think religion is a personal choice and sexual orientation isn't? Sorry, I cannot hang out with misguided people such as yourself!"

I can literally take anything you say and find any excuse to disassociate myself from you. The problem is when people don't talk to each other and it's worse when they disassociate based on topics they likely have no idea about.

Is it a personal choice though? If in the morning I decide between wearing a blue shirt or a red shirt, that's arguably a matter of personal choice, but deciding to believe in God is as much a 'personal choice' as deciding to believe in gravity or deciding to believe in homeopathy.

It’s reasonable to equate them. Both are protected classes.

Yes, it's reasonable to equate them in the context of employment discrimination. That's what "protected class" protects from.

Isn’t that the context here?
