First, I would say, if you had good relationships in the Baptist church that you left, it would be good to keep sharing with the people you found to be genuinely Christian. And see where they went. But at least keep in touch, maybe have a home group, pray together, talk on the phone . . . something.
And, now, even if you did not continue beneficial relationships, you can find people who are good Christian examples, who help you. Then see where they go to church. Or, visit a church and see if you discover ones who are sound people in God's love and who help you get more with God and more into loving any and all people the way Jesus wants.
So, then, of course you don't want ones who are just nice and friendly, but who help you get real correction to live how the Bible says to submit to God and love.
But, then, I would say do not judge a group or church only by what wrong people are doing, but see if there are ones truly gentle and humble . . . including mature senior examples. Ones younger might be able to do some good, but we need our mature senior examples of the faith and how to relate in love.
Also, by the way, you might visit the ministries for children and younger people, and see who is ministering there. My opinion is we need to have our mature people with younger people, not only babysitters.
And if you find you believe in what maturely Christian people are doing in a church, join them in their vision and hope. Yes, there may be even leaders who are not with it, not mature, even wrong, but there can be the really exemplary people in the same church . . . ones who have hope for any and all others, who do not give up on ones less mature and who even are wrong > love "hopes all things" (in 1 Corinthians 13:7). You need people like this, who don't quit; they can help you get ready for marriage, or to do better in marriage.
