Airbnb Host Unfair to Same-Sex Couples?

I recently requested and booked a one-night stay at a place in Anaheim. I messaged the host asking if he could accommodate me and my girlfriend for April 15th and check out on the 16th, to which his response the next morning after was an apology, stating it was two nights minimum. This was false. On his profile of the guest suite, it states one night minimum.

I’ve read plenty of reviews from other guests who were able to book a one-night stay at his place with no problems. I feel like this host is BSing and don’t want to host a lesbian couple.

The next morning, I looked at his listing and the 16th was booked. That was only one night. I called Airbnb’s specialist team and also messaged them the complaint. I am waiting to hear back from the case manager. This frustrates me because I have good reviews on my end and no reports of being a bad guest.
