Aloha
silent treatment to me at least is a no no. It can be so damaging to a sub and all the more if it is unexplained. In such circumstance I would call it abuse. When explained I think it can often do more harm than good and it is a questionable way to treat anyone I think.
I have chatted to many subs just left dazed and confused and down right hurt.
I realise that what I might find a highly questionable preactice others might see as neccessary and I am all for people's right to their opinion. However I only hold this view when it does not harm others and I see little evidence of that.
To me it says more about the punisher than the punished.
(I do make a distinction here between times when us males just have to go to our cave to simmer down or do whatever we do there as opposed to just blocking someone out completely)
