"the fact of being who or what a person or thing is."
I have to love people these days trying to downplay sexuality. It's obviously part of people's identity.
It's your fucking sexuality that you are born with. It defines with who you want to have sex with, not who you are. Might as well make that little mole on my back or my natural hair color my identity. You can't downplay sexuality because it doesn't matter one bit in the first place.
If you demand respect or gratitude for your volunteer work, you're doing volunteering wrong.
