I don't think the argument is about making people "like" gay people. It's about allowing people to be who they are (or who they choose to be if that's your ideology) without fear of persecution or being deprived of basic human rights.

If you truly subscribe to the notion of 'freedom' that so many conservatives so loudly tout, then it makes no difference whether sexuality s a choice or not (just as is the case with your religious beliefs). You can't reconcile the idea of "freedom" with laws that infringe on those freedoms. That's not "freedom" in any sense of the word.

Given your argument however, isn't it equally plausible that "the conservative community claims it is NOT decided by nature but simply individual preference, so they can maintain the force to disenfranchise those people"?
