Going to Facebook (and having mix-gender “friends”) is just the same “issur d’Oraissa” as eating treif, as the Torah clearly writes “??? ????? ???? ????? ????? ??????”, and “?????? ?? ??? ????? ???????” (the former you know what it means, the latter refers to the chiyuv d’Oraissa to refrain from gender taaruves)
