FNY- you wanna know why i think people think its fine. True, less people said so than i thought with my original scan of this thread.
you said “Being that everything is muttar until proven assur, and being that no credible source was given citing an issur [yet], this thread points to the assumption that mixed gyms are muttar. If you disagree, prove your point. As always, please consult with a rabbi before providing practical advice toward chumros and even toward kulos.” this seems like your main argument.
First, like some have already said, our topic is something that, to my knowledge, most orthodox consider a problem. Next, i agree with you that just being machmir always without finding whether something is really asur or not is wrong. The same way something assur is assur, something may be muttar and people shudnt be stopped from doing whats ok. Again, saying im not a rabbi. Due to the fact that none of us here are, this attitude doesnt work here.
You bring up good points, i dont have time and patience to respond right now to the rest of what you wrote. Just saying for now that on a largescale issue like this, i dont think people shud say “hey, noone proved it assur”
Flatbusher– i dont know how your rant relates to anything i said. BTW I admitted from the get-go that i’m a rasha. That doesnt mean i shudnt stand up when i think a large amount of people are being led in the wrong way regarding issues of kedusha and the flippancy in which it’s made away.
