Do you not see how those two things are very closely related? Two things don’t need to be exactly the same for a double standard to exist. Only autists think that.
For example, fudds. They’ll defend their right to own their hunting rifles and 1911s to their last breath, but when someone wants to buy an AR15, they’ll demand a million hoops or an outright ban. Those two things aren’t exactly the same, but there’s a very clear double standard there.
Again, for the third time, relationships are purely sexual to you. When you’re complaining about a lack of female effort, you’re complaining about them viewing relationships as purely sexual and “putting in less effort” as a result. That is a double standard.
