He wasn't attacking women, he was sharing his dislike of Kendall herself, which is fine and you're not one to talk because you've written comments about female singers you don't like before.
Don't be so extra, he was calling out the whole section of privileged white kids.
I didn't even watch it because his music is enough (rapping about raping pregnant women, wanting to his Rihanna, etc) so i expected him to make more petty comments.
