The gender stereotype it's exaggerating is not only that women talk too much, but that their talking is pointless and uninteresting. As gender stereotypes go, it's actually pretty far up the offensiveness list.
I took it as a joke about "women want to talk / empathize about the problem they're having, not talk about how you'd fix it." Which can be true in social contexts, but is totally absurd to apply to a sinking ship, hence the humor.
But it's 100% possible that I'm reading too much into it and the joke was just "Haha women talk a lot about pointless things," in which case yeah, I probably wouldn't have laughed.
From another less popular angle, "Men are worth less than women and children and thus don't get to be on a lifeboat". See now everyone gets to be offended.
I agree to an extent, but was taking a deliberately condescending tone because "I hunted through twitter and found something unrelated to get offended by" didn't strike me as being a useful debate to bring in here. But I probably should have communicated that in a less passive-agressive way.
> I feel fine and this is one of those cases where I know I'm right
Please come down from your high horse. Seriously, as someone who has actually been bullied a bit, calling this sexism seems like a giant misunderstanding.
Here's another one to balance the scales: How many men does it take to screw in a light bulb? Just one, but you'll have to ask him 50 times.
Feel better now?
