If the situation were reversed, and it didn't feel problematic to you - would it still be problematic? You may feel that way because you're a woman... but what about men who have been sexually abused by their mothers? What about the problematic inicidents of paedophilia perpetrated by female teachers on underage boys? It may not feel the same to them - Lizzos comments may feel problematic and creepy
You can't have one rule for older men and younger woman, and older women with younger men - becuase there are people who find both those things problematic and should also be listened to. Those are the people that we should be hearing from....
or not...because in reality, it's often a silly joke both ways - and identity politics plays havoc with the ability of people from all ages, genders and walks of life to interact in a fun way without it being retrospectively weaponised for offense.
