jbaldy22 -“and i dont view it as something inherently good or bad. I still have not really heard any cogent arguments to the contrary.”
It isn’t inherently bad -it’s the Seviva. Take a hall in the middle of the city -it’s just a hall. Add a rock band & add Goyim dancing not wearing Tzinus clothing and I won’t mention what else. Now a Jew doesn’t belong there, even if they are doing something Kosher like a Shidduch Date, because it’s a bad Seviva.
Do you know any really Frum guys who would take dates to a disco place? I don’t think so. Facebook is the same thing, just in the privacy of your home.
