Remix if the LGBTQ+ Community is welcome on your Account A: of course they are allowed! (I myself might be part of the community~) I am also friends with lots of people who are LGBTQ+ and they are great to be around!
Remember, just because someone is LGBTQ+ does not mean they are bad or weird. They are just a normal person no different from you. This is not anything worth judging them for; a person's identity does not define them and should not affect how you view them as a person.
