Gay rights, by definition are defined by what you have sex with.
Which to some, who you CHOOSE to have sex with does not qualify as a “right”.
Bisexuals are born that way and they want to love people of both sexes.
Science can be a bit pesky here. While there are gay Byron’s and gay George’s, some gay Don’s and even some gay Gary’s; there is not any credible study that has identified any gay “gene”.
