Personally, I'm for this meeting. Were the meeting to take place off to the side, and not be flagged as a main event, I'm sure there would be no problem. However, if it were to be flagged at all, rather than just the fact that it exists being known, it would not be too welcome by those who choose not to practice a religion.

But yeah, by all means, go for it. I've seen and felt the effects of prayer, so they're welcome by me.
