One thing I think people need to remember is this. Okay, I had one housemate, who was a homophobe and was generally unpleasant, and he seemed to want total solitude. He's an extreme example, as most introverts at least need some people. And sometimes people can think someone's chatty, when they're not, but the person might be chatty because the person with whom they're talking is interesting to them, or the topic of conversation is.
Which brings me to a sub-group within the LGBTIQA Community, autistics. If you went to a Pride event, and then you went to an Australian Coles or Woolworths between 10:30am and 11:30am on a Tuesday, you may see some of the same people, but some of them might have been nursing social hangovers after a Pride Event. Many autistic people have sensory overload, hence supermarkets have catered to us, whereas Pride Events are loud and bright.
