Smoking pot would do the same thing. Playing a board game also. Are we now going to say that teasing, drinking, smoking pot, and playing a board game are equal?
I can't tell if I'm getting trolled because of your username or not, but it seems to fit here.
Actually, you basically just rephrased my point: the argument I was responding to applies to everything from mild dysfunction (inter-generational family addictions being passed down and celebrated) to perfectly benign (similar habits regarding board games instead of drugs).
Hence, it applying to teasing doesn't say anything at all about whether or not teasing is a good thing -- the argument applies to nearly anything at all, both functional and dysfunctional.
