If your church allowed gays would you still go to your church?

Yes indeed. I've been in a church. Nobody can stop you. We don't have a sign over our heads. I didn't get struck with a bolt of lightning either. 

I attended UU for years and they have had gay marriage for 49 years now officially, but even before that they were pretty welcoming.

Allowing and welcoming people who are gay to come to church is a good thing. But if my church encouraged a gay relationship then I would consider leaving since they’d be going against God’s Word, and I trust God’s wisdom more than people’s ideas. I’d bring it up with my pastor first before leaving though because I love the people who go to my church, they’re like family, and if there were friends coming who were gay, I wouldn’t want them to be deceived. We all need to be born again and receive God’s Holy Spirit to find out who we were designed in God’s heart to be before sin brought corruption to the world. Jesus came to redeem us, fill us with His eternal Holy Spirit, and restore us to His image.

Everyone is welcome at any real Church, sinners are not allowed to lead in a real Church.

yes,  and i know two girls that are married there

Allowing gays is allowed, in the lds church, but they have to be repentant and they have to abstain from the life style, people can repent

Yes.  The minimum...

The last time I checked there is no "gay metal detector" that can tell what someone's sexual preference is before someone walks in a door. If the gay person flaunts their sin in front of the congregration then the other members have a right to say something against them

Gay people are allowed to go to church. If you're asking "What churches support gay people?" I can answer you: They do exist, they're just less common.
