Fantastic! Yes, the song can be interpreted as misogynistic IF you related to the lyrics in a misogynistic way!
This is exactly what happened to me. I DID think that Taylor was "not like other girls" , just like me! And I thought that made me "more pure" or "better" or whatever bs patriarchal message I was being fed. The reality is, that's a reflection of myself and my attitude towards women at the time. (My misogyny)
Because there is just not enough context for us to analyze whether Taylor's lyrical intention was to compare and shame the gf or just state facts.
Of course, it also makes sense to say that there are misogynistic undertones, because in 2008 when it came out, we were all basically not-like-other-girls-ing it up! Right? Like, that was THE TROPE at the time. 2000-2010 was just straight up messy, and YBWM is a product of this.
However, all we can do is speculate what Taylor was saying. I do 100% agree that our perceptions say more about us. Thank you for this thought provoking piece!
