Why do people like to post about something/someone popular they consider overrated?

13. My issues with Madonna critics are usually because

their criticism has to do with ageism, sexism, or slut-shaming.

That's what bothers me.

It can also bug me when the criticism is just plain dumb. For example: I read a critique of her "Madame X" tour where the critic complained that there were "too many songs off the Madam X album". I mean really! The tour was to support the album! That's how rock tours work, generally. Duh!

I don't love everything Madonna has done. She's had bad albums (Hard Candy), weak albums (Erotica), and songs that are just plain garbage. She's also said / done stupid and silly things over her career. All of that is fine to critique.
I just have no patience for the criticism that is bigoted or ignorant in nature.

I feel sad for anyone who would take online forum comments seriously enough to be bothered by them more than a minute or two. I certainly wouldn't want any hardcore Eagles fan to throw out their record collection just because I personally find them to be torture to listen to.
