Katy Perry and precursors

In Katy Perry's "You're So Gay," she complains about a boyfriend who feels unhappy & likes complaining songs that ask for realness and asks him to be more real.
Also hypocritical is how in "Hot 'n Cold" she complains that a guy is indecisive while in "I Kissed a Girl" she did it just to try and liked it but doesn't want to have any of the consequences of her boyfriend finding out. Looks like she thinks girls shouldn't be too real with their romantic partners.
While these inconsistencies are annoying, it's worthwhile to look at precedents.
Her message and attitude reminds me of Keira Knightley and Avril Lavigne.
More specifically,
-Her experimentation in IKaG does seem to follow Paul McCartney's (in "Yesterday") lament that "Yesterday Love was such an easy game to play" in "Yesterday"
-Her claim of objectivity "You're wrong when its right" in HnC can be compared to The Beatles' demand for a one-way stand-down in "We Can Work It Out"
As more people hear this sort of thinking applied to men, they may realize it's bad generally (or, conversely, that impulsiveness is good for everyone). But I think most fans don't consider the attitudes bad.
Quality of art isn't synonymous with message, but the latter should be considered. The mean-spirited and self-contradictory nature of the song sink YSG, the repetitivity and simplicity sink IKaG (especially coupled with how much it sounds like a knockoff of Gary Glitter's "Rock and Roll"), while the beats make HnC somewhat entertaining, but it's been overplayed (as have some songs from other artists). Perhaps if YSG was played to a similar extent, there'd be more realization of the down-putting aspects of the singer.
