In my opinionm this is one of those meme's thats just been blown out of proportion. Such as trolling, originally it was a certain way of annoying people, not just saying 'I slept with your mum' is considered trolling.
This particular meme was made to get back at girls such as this (and this is an actual quote)
*girls facebook statuses* OMG IM SUCH A GAMER
Boy: Sweet, looking forward to E3?
Girl: Whats that?
Boy: its a place where everyone shows the latest games
Girl: Sounds sad
Boy: oh...
Girl: Stop talking to me you saddo.
There are also the people who take pictures of themselves with glasses etc, trying to get attention to the fact they 'think' they are nerds because they watched a mainstream Marvel film or something, (When, In my coummunity anyway, most of these girls used to harass me for being a so called 'nerd')
(I say so called because I don't believe in stereotypes, yes I play games more than other people, Im just a guy who likes games, not a nerd, stop labelling me just so you can bully me)
(This particular case also applies to converse and vans shoes, I was called an emo for wearing them a few years ago, whereas now they're trendy and its fine to wear them)
But now its been blown out of proportion to mean almost any girl interested in anything related to the topic.
On a related note, gamer girls are also similar to this. WHILE THIS DOESN'T APPLY TO ALL GIRLS, The amount of times I would be playing a pc game, and a girl would join and always bring her gender into it without any help from anyone else, and I would get ready to disconnect as everyone would stop playing seriously and devote their attention to this fact. Obviously I can understand sometimes your gender comes into the conversation, but does everyone need to know you're a girl as soon as you join a game?
I actually remember a conversation In counter strike go which made me laugh
Girl: Hey, Im a girl
User 1: And?
User 2: I dont care
Girl: Doesn't anyone care?
User 2: no
Girl: ugh, jerks
*Girl has left the game*
NOW I know theres alot of girls out there that are not like this, and I respect you. Infact, to all the girls Ive played with without knowing your gender, I salute you.
Meh, its not just these areas though. It happens throughout life everywhere. Girls get more views on youtube (for games and non game topcis) even covers of songs get more attention if you're a girl. Its just leads back to girls being sexual objects in the media again.
And I hate every part of it. We're supposed to be equal, dam hormones changing this. (shakes fist)
Just a quick disclaimer, some of this is opinion, some of this is explaining the general idea, so sorry if I offend anyone
Alot of stuff is taken from personal experience, and due to the size of the post, haven't been able to read everyones reply.
EDIT: I think yahtzee put it best, I can't find where he said it, but he basically said 'Some days I go out, some days I play games. I play games on the bus to pass the time. I may also go out and get drunk, or have a night in with my friends playing games. But I am not a gamer, or geek, I am a guy who plays games, and im a NORMAL person.
