[worst-case scenario]

Well, there was the ancient Roman Republic and Empire, which lasted for close to 1,000 years, depending on how you count it. They sanctioned homosexual relationships between men, as well as between men and adolescent boys, but they were often between freemen and slaves or servants. Documentation of lesbian relationships isn’t as frequent, but the attitude appears to have been that these were also permitted, provided they were discreet.

I seem to recall that the Romans experimented with allowing homosexuality in their military, the idea being that they were far from home and needed to quench their sexual desires. But it proved to be a big mistake and they reversed the policy. I'm aware of Roman debauchery, but don't recall acceptance of homosexuality. Perhaps that was towards the end of the empire? I'm open to being educated on the matter, if you care to spend the time.

As far as lesbians go, most people find them far less offensive than gay men. Even the Bible makes a distinction. Most people aren't nearly as offended by lesbians as they are by gay men. That's been the case for thousands of years. I don't know if you're religious, but nevertheless some passages in the Bible make it clear than man on man sex is an abomination, and those texts have been around for a long time.

In present times when someone says that they find homosexuality repulsive there talking about gay men the majority of the time.
