Churches, in my experience, have been terrible places to meet people for dating.
Many single groups are nothing more than 'lonely heart clubs' where people sit around and complain about all their problems.
Others are cliquish to the point where independent folks simply will not tolerate their games, and hence leave.
And many are just too puritanical about dating (such as no kissing or discussing fantasies).
And of course, there is the small percentage of charlatans who act religious by quoting scripture and lying to women in churches. A lot of women are pretty gullible to this scheme.
About a couple of years ago i went to a baptist church singles group..i was so incredibly unorganized....they didn't even have anyone to welcome visitors or anything...almost felt like i was intruding on their cliques.
