gwen This sounds like misbehavior regardless of their sexuality.
For me, it is. The problem is that it appears to me that some people feel that they have the right to misbehave because they a re different; others, and there are many of them in contrary to the first group, feel offended when you ask people to behave normal in public because they automatically assume you to be a sexist just because you complain about some LGBTQ+ people who do misbehave.
So, many of them demand that we don't stigmatise them, but at the same time they do stigmatise us - that's a problem their sub-society needs to face.
