froggie: you clearly are fixated on your misunderstanding of what I said in re mixed gyms. From a logical perspective one must build from ground zero. From a practical perspective one must be cautious and use common sense. I was coming from a logical perspective, discussing theory. Further, I requested sources numerous times before suggesting that if the thread implied anything it implied heter. Emphasis on the word if.
An aside counter to your absurd argument: I think your breathing is assur. Stop! How dare you play around with such serious issurim. Everything is assur until proven muttar. Your breathing is like stealing and cheeseburgers. Because it is.
