Monk, dude, stop playing Mr. Responsible and let people discuss what they want. I am sure all participants are adults and capable of deciding for themselves.
Believe it or not we are always responsible for even micro-interaction with ppl.
I suggest you study subject of "ra'eea"(If I pronounce it right)
You will be questioned for ever time you could have an impact on an other individual.
And smart guy like your self, would be held more accountable.
Thanks.
