Since you brought it up.
Any Christian following Christ teachings should know better than to shun gays. Those who do are wrong.
In Christ eyes we are all sinners and no sin is worse than another. So even if a Christian believes homosexuality is a sin, it is no worse than their own sins. Christ loves and accepts all sinners be them gay or not. Like all of us, homosexuals can admit they are sinners, accept Christ, and they are saved. Christ will not turn them away.
And it is not our place to judge others. Those who do are out of line.
My church welcomes homosexuals or anyone else.
