Why is it gay to like ABBA?

I love knowing me, knowing you, and dancing queen. I'm a 16 yearold dude but I listen to aphex twin, kraftwerk, the prodigy, ministry, the crystal method, metallica, sublime, Elton John, van Morrison, venetian snares, MJ, new order, the police, but if I throw a lil ABBA in to it, it makes me gay? Like honestly? Why?
