Do you really not think there's any difference?
Between frivolous discussion and referral links? I absolutely believe there is a huge difference.
There are many who would say that if you are bothered by an underwear discussion, you might need to move up in waist size from a 34 to a 36.
I don't think so. I appreciate that every one has different sensitivities as to what constitutes frivolous, offensive, or inappropriate discussion. You're welcome to have high standards. I just think that you'd be better off to just ignore that which you *personally* find troublesome instead of complaining or comparing it to egregious rule breaking.
