I support the LGBTQ+ community. I think the government has no place ruling over a consenting adult's ability to be who they are and love anyone they want to love, short of infringing on the rights of others. I will never support legislation that enhances the ability to cut down on the rights of citizens.
I don't think the issue needs to be any more complicated than the golden rule - treat others as you wish to be treated. Let love be love and people be free to express themselves.
