When someone judgingly says that homosexual relationships are a choice...

I'm going to assume that person [i]chooses[/i] to only date the opposite sex, meaning they are attracted to both sexes. (Otherwise it wouldn't be a choice after all.)

That in turn means they must agree bisexuality is natural, and so we are on the same page. This way I can respect their [i]lifestyle[/i] of only engaging in heterosexual relationships. 😌
