Because it reeks of sexism. The premise is that the person could be a poser (not knowing Megadeth songs), and this is applied mostly to women, especially when it's based on just wearing a t-shirt : a dude with a metal shirt leads to "cool, a fellow metalhead", a women with a metal shirt leads to "uh, is she a poser ?".

The conclusion of being extra-fair about confusing two major bands, just after being overly picky, also implies that you have a good reason to change your mindset, and this stinks of sexist implications too.

Metalhead girls get this question way too often. If it one day crosses your mind to ask it, please at least rephrase it so it's not accusatory. Just ask about their musical tastes or if they saw them live, like you would do with any one but not this fucking "name one song".

Its the high school level misogyny of 'women cant be fans' and its an overused 'joke'

Im going to guess because boobs.

Oh I can think of so many reasons to downvote this!

The whole "name 3 songs" thing is sexist, it's usually said to women in band shirts. It's boring and old.

It's had a shit filter applied to her face. I see the exact same face everywhere. She looks like a Barbie doll.

Why metal guys? Are they more shallow than the general population? I didn't know that was a stereotype and I've been to my share of metal festivals.

But that's nothing compared to the fact it's not very funny. It's Facebook tier humour. Haha men are blind when boobies are involved.
