Yes the management and staff of my gal friend's apartment building (where I lived for 10 years) is mostly all LGBTQ people. Couple of management/staff people where I live now are LGBTQ as well.
Not only do I know them, I'm closely related to a few. My own daughter identifies as bisexual, has chosen a man as her life partner but has been with a few women as well. Her bestie, also bi, had several boyfriends as a teen and young woman, is in a long-term relationship with a woman - was engaged to be married to another woman but she broke it off when her fiancee became controlling.
I have one cousin who is bisexual. She's in an opposite-sex marriage. I have another cousin who is a lesbian. She's in a same-sex marriage. I went to her wedding.
