I find the choice of phrase irritating, and the accusation generally unfounded.
When men disagree and are twatty and rude on websites, they are just Doing The Internet.
When it's women behaving in the same way, somebody ALWAYS compares them to Queen Bees at school, or bullying bjitches or whatever...it pisses me off beyond belief, and I find myself mentally deducting credibility points from anybody who uses the word "playground", usually with the breathless anticipation of being commended for their startlingly original and incisive social observation. It is a really tired and over-used comparison.
And it NEVER gets said about men, only women. So it's sexist as well as crap.
I am illing and taking to my bed for a bit, but I want you to tell me if I am being grumpy and unreasonable, or if you know what I mean and saying it should be banned as the metaphor of dullards. TIA...
