How is that any different from you 'hating" on people because they don't believe in the same things you do?
Believing in something is an active choice. Believing in something that is demonstrably false is an act of sustained stupidity.
Gay don't choose to be gay any more than Blacks choose to be black.
The homophobes argument against homosexuality usually consists of "God Says its Bad", and "I think it's Icky". That's the whole substance of their argument.
Now, you might not like what I say about the Mormons, but I back it up with critical looks at their beliefs and history... you know, like Joseph Smith was run out of four different states for running various cons before the folks here in IL put him out of his misery. Or that he was having sex with mulitple teenage girls. Or he outright lied about the Book of Abraham being a first hand account of Abraham's time in Egypt.
Crazy is thinking the best solution to deciding who's feelings matter more is letting government decide.
Except we do that all the time. That's why we have a million lawyers and courts and lots of legalize.
So on one side, we have the Cryer-Bowman's, a couple who were seeking to get legally married to protect the interests of two special needs children they had adopted. Who went into a shop after being invited and were subjected to verbal abuse and denial of service based on who they were.

Some Wife-beating asshole who sabotaged his wife's business so he could suck up to Christian nutters across the country.
Pretty easy to decide who the wronged party here is.
