That's a rather over-broad generalization. I used to run a local Star Trek club in the '80s and '90s, and our membership included everyone from atheist (me) to extremely religious, and several people who either didn't care one way or the other, or just didn't see any reason to tell us what they believed or didn't believe. Somehow we all managed to get along, and the most religious person and I were the ones who wrote and edited most of the content for the club fanzine. She's the one who came up with the racier stuff in the Next Gen soap opera parody we wrote. Between that and making our own uniforms ("Yesterday's Enterprise" hadn't even been written at that time so we just used our imaginations while frustrating the saleslady at the fabric store as to why we refused to buy anything in red), playing a joke on someone at a convention (they ended up with a lot of tribbles)... we had a blast - of the good, clean fun sort.So lets tread carefully with this again, as the fanbase is rabidly anti-religion to the point it is hilarious and sad.
No "militant, rabid" actions occurred whatsoever.
