In this case I could see a case where it could seem directly threatening: the more men that express wanting to be provided for, instead of working, the smaller the pool of potential partners for them. Traditionally, expressing that or acting on it would be a big social/reputational risk for a man.

Whether or not that's really true - "anyone who's going to be miserable because they're working full time and you don't isn't right for you" or somesuch - I could certainly see people feeling like it impacts them. It might feel like "oh, being a woman still has these other disadvantages that aren't fully eliminated, and now you're wanting me to give up something I see as one of the advantages in exchange for nothing."
