Declared normal? By who exactly are "they" trying to get homosexuality declared to be normal by? Ah wait...they aren't.
And exactly what laws are they trying to get which "support only their sexual behavior"?
They have been trying for the last 10 years to get special laws passed in numerous States. Laws that would give them special status if fired, for hiring, for renting or buying, special status on par with blacks. They even make the same claims that somehow they are entitled because they are just like blacks when it comes to past discrimination and behavior. Which is of course an interesting feat since Homosexual behavior is not skin color and while there are a few people that are so queer you can tell most are not. Special laws that are not required since they already have all the same protections as everyone else.
Further they have derailed any effort to compromise and create Civil Union laws that would give them everything they claim they are lacking. Instead demanding the term marriage be used.
