Bill said--But, Dark, like all things -- there is a proper time and place. Unless, like Fred Phelps and his Westboro bunch -- your purpose is solely to disrupt and be a nuisance -- and not to learn.
I would not go with the sole intention of being disruptive, no. However I do believe that my questions and comments would not be welcome, so in the end it would probably be perceived as disruptive.
Now if your choice was jail or a weekly Atheist meeting which would you choose and if you chose the atheist meeting would you sit quietly and learn?
