Assume for a moment that you're right. Assume, even, that the original poster agrees with you.
Now, re-read the post. You'll see that the poster doesn't have a thin skin; they're just sharing something that happens all the time.
The blatant stuff is, perhaps, easier to deal with because you can let off steam and have a rant. It's the gradual drip drip drip of every day comments - comments that your colleagues don't get, and the only reason they don't get them is because they are male - that just wears you down.
UK Comedian Josie Long has a good talk about it here:

I don't get the idea that these are weak people, or oversensitive, or they have weak skins. I get the impression that they've just had enough.
(I hope you see that I've tried to engage your argument and not just attack you. Personally, I really dislike the idea of telling people that "jerks are out there and it'll take years to change them so sorry, deal with it.)
