You're entitled to your own opinion, but I personally think you could have expressed it not so harshly. You were being very rude when mari poured her heart and soul out to us for advice. She didn't do that to get rude comments. There are many other more polite adult ways your words could have been worded that would not have come across as rude.
Fluff is everywhere that women congregate. BDSM isn't about just whips, chains and pain. There is a lot more to it, including fluff. Your opinion doesn't have to be warm and fluffy but it needs to be expressed in a manner befitting adults.
