Sure, I'm not arguing about whether one is better than another. I'm arguing about whether people who want to do a harmful and unacceptable thing should be allowed to do it in clearly designated premises.

I'm yet to understand why that differs from racism - it's easy to construct a similar argument in the other case. For instance "if racists were allowed to drink in whites-only pubs, there'd be less racial violence caused by forcing people who hate each other to get drunk in close proximity to each other".
