LDS is not alone in condemning homosexual sodomy. Essentially all major religions teach the same thing.
No "Christian" or member of CJCLDS hates anyone because of their sexual inclinations. Indeed, the vast majority of married men - Christian or not - are inclined to copulate with attractive women who are not their wives on a regular basis.
But sinful ACTS are more than an inclination. We are all commanded to restrain ourselves and not give in to our sinful inclinations and desires.
No one cares who you want to copulate with. In a working career of more than 55 years, I never had occasion to ask a co-worker who they were married to, or what gender that person might be, or who they were living with, or in an intimate relationship with, or who they wanted to ****. It doesn't come up unless someone forces it to come up.
When you are "openly gay," or are married to another man, you are advertising the fact that you are inclined to engage in homosexual sodomy, and that you do so whenever possible. Again, this goes beyond having homosexual inclinations - which you may be powerless to change. As a result, people who find that BEHAVIOR to be sinful may very well DISCRIMINATE against you. You have chosen to flout your immorality; They may choose to shun you because of it. Deal with it.
If this is the lifestyle you choose, you have an obligation to yourself and everybody else to seek out venues where that lifestyle is welcome. Lord knows there are enough of them. There are college campuses that are theoretically founded in religions that unequivocally condemn homosexual sodomy (e.g., Marquette, Georgetown, Fordham), that have thriving LGBT communities. Go there.
And leave BYU the **** alone.
