CMV: Businesses should not be allowed to discriminate based on race, sex, national origin, sexual orientation, etc.

1. You can effectively run people out of town just because of who they are by withholding essential services from them. You could also basically ban blacks, gays, etc. from town if all of the hotels decided not to accommodate them. This happened before the Civil Rights Act, something you have to oppose if you're being consistent. That's why when JFK came up with the Civil Rights Act he wanted to outlaw discrimination by private owners of public accommodation.

2. It is a dangerous precedent to set. What if I interpret my holy book in a certain way that I believe I should pay certain people below the minimum wage? Isn't the minimum wage violating my religious freedom? If you actually want to be consistent, then minimum wage shouldn't be required either.

3. You never know when a new class of people could become the new hated group. Imagine if, hypothetically, we went to war with China, or there was a terrorist attack. There would certainly be a lot of people who would refuse service to people of these nationalities. So you can't just say that we've forever moved past it.

4. Private owners of public accommodation (retail stores, rental establishments, recreational facilities) are already not allowed to discriminate based on race, color, religion, or national origin according to the Civil Rights Act of 1964. This is very important legislation and will have to be repealed is you disagree.

Let me make myself clear: I think businesses should be allowed to refuse service based on *what the service is*, not who is asking to be served. So a bakery can refuse to bake a cake shaped like a dick or something. I also think if a service is purely religious, like a wedding ceremony, a religious establishment can refuse that service.

At a college campus, lets say that the law technically allows minors to be in a drinking establishment so long as they are not being served alcohol. However, to help prevent prevent older +21 students from passing drinks to younger ones (which happens frequently and is hard to prevent), the college bar decides simply to not allow anyone under 21 at the bar after 8pm. 

This is clear cut age discrimination, so would you argue that the bar owners should be fined for taking this precautionary measure to help prevent underage drinking?
