Bottom line (no pun intended) - no one owes you approval of your lifestyle. If you want the approval of a particular person or group, behave in such a manner as to earn that approval. If you want the respect of others for your life choices, you must first be willing to grant them the same respect. Can you really respect those who find your lifestyle to be immoral? I suspect the answer would be no, yet you demand they respect you. Ain't gonna happen.
Eventually you'll learn that you can't please everyone, and that demands that they respect your lifestyle will merely lead to less respect. At that point you can either become sullen and sulky, or you can set your sights a bit lower. Most of us find tolerance of our lifestyles and respect for our G-d given rights to be quite enough without demanding that others respect our choices, and I fail to see why a homosexual or bisexual should be any different. I have no problem with a fundamentalist telling me I shouldn't have the occasional whiskey or that I should go to church every Sunday or watch R-rated movies or play violent video games, as long as they are not trying to infringe on my rights to make those decisions for myself. Certainly zsdersw has no problem with people believing homosexuality is immoral; his problem is with people who try to legally constrict his behavior to comply with their beliefs where there is no pressing societal need* to do so. Hopefully you too will realize that the beliefs and approval of others are not usually germane to your own happiness. Your neighbor believing that your lifestyle is immoral will not prevent you from seeking happiness; your preoccupation with what your neighbor thinks about your lifestyle will.
*That's not a hard and fast rule. If your preference is to kill and cannibalize your lovers, clearly there is a pressing societal need to infringe on your freedom. My own preference is to club senseless those who pull out in front of me because they "didn't notice" my bike or run me out of the road because they can't put down the F'n phone; I can accept that society has a pressing societal need to infringe on my freedom to do so.
