While there is exaggeration, I agree there isn't an army of female hating men and people like Sarkeesian are just exploring the situations for their own interest, I like to state there was and still is a problem portraiting women and particular sets of people. In case of women, it is still unbelievable to me how unrealistic most characters portraited in games still are. I do believe this is however for the lack of women and the lack of observation and analysis power of the men in charge (not men in general) in writing the plots and characters.
The problem with people like Sarkeesian is that instead of having a conversation, she exaggerates and puts things in a perspective that helps no one. It creates resentment in the general community by pandering to outrage for things, that for the great part aren't even there. And the repercussions go beyond games - because of people like her many don't take the femenist struggle serious or simply resent it at well. It ends up being exceptionally detrimental, specially in a time of need, where there is a president in place in the US that repeatedly harassed women, a vice president that believes the women role on society should be constraint and a government that's been removing supports for things like family planning, or in other places in the world where women have it much harder.
I do believe character placement for minorities can help, however. Again I don't think it's sexist or racist or whatever not to do it, and it's perfectly alright to have a white male straight set of characters, specially if you already have it, but it doesn't ruin anything to have different sets. The trouble I have with it is again the lack o realism it goes sometimes in creating them. Many of the times, writers seem to fail to understand of what would actually be a motivation or how would a real person react in a certain situation - it doesn't help to accept and normalize others if you fail to portrait them
I don't think I can say it better than pustal did - but I'd also like to take a look at movements in society.
- The movement thats pushing beyond whats socially acceptable at a certain point.
- The reaction of the general public and when a movements positions become somewhat accepted.
- The commercialization of said ideals.
Its at the - when decisions are made to please a broader audience by using social progressive trends as a backdrop for being relevant, where the "not going with it" might be appropriate.
In Europe f.e. there was "the girl on page 3" that has been used by newly invented gossip papers as a mode to attract readers - but was "rectified" as them doing their part in the societal struggle of women to become more independent and free. The struggle was real, and a movement at the time as well - the use of barebreasted women to sell newspaper wasnt necessarily related though.
On the other hand, its entirely ok, even proper - to do race or gender or secondary identity swaps - if the "archtype" demands it to be more relevant. Or at least isn't hurt by it. Thats an argument for artistic integrity.
If the story or alegory you want to tell calls for it, or benefits from it - do it. It might shock a few people - but if they are connected to the archetypal nature of that figure, and thats still present, they'll still remain connected - and to them it might even become a "perspective swap".
If you are doing it, because it is the hip thing to do, or you are going by formula - and might have a certain quota in mind - chances are, that the archetype is hurt, people who liked it will disconnect - and resentments will arise.
Which brings us exactly to the SJW movement - and the backlash they are facing. Even in academia.
Now - on the movement part. There will always be gurus, and followers, there will always be gifted populists, there will always be power structures within the movement, and there will always be figureheads and also "abuse" in some sense. If and when a "thing" sticks has to do with the argument, the reactions to the argument, and timing.
The saving grace here is, that democratic societies - over the long term, seem to move forward, as a result of social struggle, they deal with it - appropriately. If too many people get caught at the fringe, the fringe moves more to the middle.
Now my comment of the day on the SJW movement:
The principle, that the more "oppressed in different aspects of you life you were - the more valuable to the movement you are" is fundamentally flawed, because it leads to people competing on grounds of "having been more oppressed". Guess what that produces...
Their modus of going after the weakest targets they could find (unprivileged "gamers", white nerds, academics that dont chant slogans...), to pronounce them the cause of their issues and lay the godmother of all guilt trips on them - hasn't been unnoticed. The comic book nerd that meets with his guy friends online - is the least of your issues in your societal struggle.
