Interesting post Joe.

All churches have an "agenda" just as all businesses have one and all embassies have one (or two;)) as well as any other organization. Just visiting shouldn't tarnish your reputation or theirs but it is wise to learn of their agenda and any hidden agendas they may have. You are right to be concerned that some may be using your appearence or visit to promote something which you do not support. Do your homework and if there is any doubt ask and make known your intent. It is always easier to not go than to have to explain yourself at a later date.

Having said that, I think that most community churches really just want their neighbors to know that they are regular folks too. They are not eating babies or stalking former members. Mostly, they are trying to overcome the bad publicity that rains down on all when some minority outfit does such things.

At these special meetings where entertainment is provided they are all there to have a good time but don't be surprised if they have a couple of "commericals" inviting folks back. After all that is why they are there, same as a business having a special event. They want cutomers to know where they are and what they can get. That's all.
