exactly!
Its just how fangirls are treated or viewed in the wider community that is a problem, as somebody else said

Fangirls are not only being told they are doing it wrong, they are also being mocked and marginalized within the larger fandom community.
and that's not cool either.
Mind you, I think its still OK to laugh at One Direction fans who got all upset and wanted to go after members of "The Who" for daring to suggest that a song was a Who ripoff, when they didn't know who The Who was to start with!!!
