It’s hard enough to be in the minority when it comes to sexuality or gender identity; one doesn’t need further policing in an already hostile society. Don’t say things like “I’m fine with your sexuality, just don’t parade it in front of me” or “Could you tone it down a little?” Encourage them to be proud, and make sure they don’t feel as if you’re judging them. If you wouldn’t say it to a straight friend, don’t say it to an LGBTQ friend.
