The color of my toothbrush is also a choice. What business or organization or government office is, or should be, allowed to discriminate on that basis?

You want to rent a new appartment. You have your money and job and credit score and reputation as a good tennant all good to go. But the owner needs to know what color your toothbrush is, and apparently yours is the wrong color.

I wonder what whether you consider religion innate or a choice? I somehow just magically predict that you currently benefit from the fact that other people allow you something you don't allow other people.

Using your clearly not ridiculous and clearly good faith argument, I should be free to, say, run a motor vehicles office in your city, and deny you a drivers license because I consider any sincere belief in any religion to be evidense of mental incapacity, and for everyone's safety we can not have irrational people operating vehicles around other people. They might decide that God told them to run someone over, or they might not value life properly because they don't think dying is really dying.

I suspect you don't think I should be allowed to make that kind of call over other people.

Tell me more about ridiculous arguments. It's truly fascinating.
