I think this is common everywhere if you ask me.

I think you get personality types that lean to the need to do it all the time, and those who do it occasionally, and those (like my ex sister in law) who refuse to take part and actively walk out of a room in which people are being bitchy.
It boils down to personality more than anything else. Men, women, you can get bitchiness in all genders and all races.
But its been an eye opener for me realising that actually moroccan women are just women, not super bitches.
I think it also boils down to the sort of culture they are forced to live as part of. In order to avoid shame, they talk of other peoples shame. Wherever the set up is partiachal, you can be sure this sort of attitude exists because a woman's worth is measured in only how men will find her acceptable.
Like a politician will bad mouth another in order to look better, advertising companies would if it wasn't against the rules (in the UK, not sure about elsewhere), and when women are the commodity, then the same tactics apply.
