Homosexuality may be a sin in the eyes of the Christian God, but to discriminate against them means you're advocating to exclude that group of sinners while supposedly every person is a sinner according to Christian scripture. As things listed as sin is not exactly illegal under American law and that this is a secular nation, I wish Christians would be more loving of gay people.
Homosexuality is clearly not a sin based on anything in reality. (And I'm not being a smart aleck...acting on it can't possibly be either.)
Don't validate the views of fringe Southrons and other third world countries.
Defining anything homosexual as sinful; the loving couple are sinful, their marriage is sinful, their friends supporting them support sin, their children live in a sinful home, the last kiss before one of them passes away is sinful makes sin so undefinable it really means nothing. All thought, all experience, all empathy must mean nothing or must be dismissed. If people want to dehumanise themselves in pursuit of god there's not much you can do about that
When a baker doesn't want to serve at a gay wedding, my interpretation is they'll serve one group of sinners but not another.
