To back up a step - no one has a problem with your reminding us that gheebat is a gunnah. No one will deny it and unfortunately, despite our best efforts, most of us partake in it on occasion. We can and should seek to improve ourselves and our aamal. But, reading your comment above - you make it sound as if:
- Desi women sit on the internet all the time
- Desi women do nothing but backbite
- Married women are not productive since they spend all of their time online - they are neglecting their children
- They only say negative things about others
These are insulting generalizations that desi women will take offense to.
Be careful what you say if and how you say it.
