To preface this, I think men should pay, I do it, and I’m fine with the expectation. However, I don’t like this specific comment because it’s a way for women to have their cake and eat it too. They want to be able to claim being progressive and non traditional, while never actually having to buck up. Women know they aren’t asking men out on first dates, this isn’t a thing. I don’t know a single couple where a woman asked the man out and then paid. So they get to say, “oh I didn’t pay because he invited me out it has nothing to do with gender”, knowing damn well she will never be asking a man out.

Additionally, “whoever invites pays” is not a social norm at least in the US. No other relationship does this apply. If I invite a friend to dinner neither of us think I am paying the whole bill. If I ask my brother to go golfing this weekend, that doesn’t mean I’m paying for him. If I meet a stranger somewhere and ask if they want to get drinks, I am not expected to pay. This doesn’t mean I won’t, but if I do it’s out of generosity not expectation.

In short just women expect men to pay but don’t want to say it with their chest.
