Some whites just want an all-white night out. Some Christians don't want to encounter Muslims. Should businesses be allowed to cater to that?

Then you aren't thinking. Sexist groups will leap on this. Racist groups. Anti-Muslim groups. And what will anyone be able to say, since there is now a legal precedent?

The point was already made.

So, a screening of Iron Man that prevented women from working or attending wouldn't bother you? It would bother me.

Your comparing women to children and the elderly? Would you have compared excluding blacks to monetary discounts in the 50's?

If a business refused to let women in because "men need time away from women" that would be sexist.

Sure…

You weren't good at it.

Discrimination is still discrimination. It's bizarre that you don't get what a can of worms this opens up.

Would you say that if a screening of the next Bond film had screenings that banned women? Would you respect that?

Bad analogy. A wedding is private. These aren't private screenings.

No males are allowed to work at those screenings, including the projectionist. And, yes, discrimination is discrimination.

"My wife agrees women should stay in the kitchen. My black servant thinks Martin Luther King, Jr. is just a trouble maker."

Yawn.

You clearly don't believe in equality.

Yawn.

Even if only two men work at Alamo Draft House (and you've clearly never been there), it would be wrong.

And if it happened to women you'd be enraged. You know you would. And guess what? So would I.

I'm always willing to acknowledge when I'm wrong, and have done so more than once on this site.

These screenings are actual gender-based discrimination. And they effect workers, not just audiences.
