In fairness, I don't think it's amusing when tm. says stuff like that either.
But whatever. I'm over this tangent. Make the OP come back!
I agree. Whether or not you think it's tongue-in-cheek, comments of that kind are all too often leveled against women who have the audacity
to argue about something. It serves to delegitimatize their (our) arguments without actually addressing them, and I'm sick of it. I get that people may not actually believe it's true or whatever, but I'm still pretty f-ing sick of it, and I think there are very few situations in which such a comment can be utilized effectively and/or comically, particularly without a friendly relationship with the individuals in question. In the interest of full disclosure, I'm probably guilty of making similar comments when they are part of a long-running dialogue but could be interpreted wrongly by bystanders as an endorsement of either the sentiment or the general practice of making such comments.
Also, I'll admit to being short on patience at the moment for those things that normally piss me off but I'm not willing to pick fights about. I'm having a Very Bad Week (but my parents are making lemon chiffon cake right now so things are looking up). That doesn't mean that it's not f-ing annoying at all times, though.
