Snoofy said, "They deserve to know they are being groomed. "
So you think repeatedly saying, "Hey you dumb ----, you are being groomed" is going to change their minds? I've never seen any evidence of that approach working. I believe it causes targeted person to dig in deeper.
Do you have evidence of that approach ever working?
Snoofy continues, "So, there's nothing wrong with letting people know what they're getting into."
OK. So let them know and move on. No need in continuing the denigration which doesn't work anyway.
