Let me clarify it simply, "Feminazi" perhaps isn't the best term, being a monstrosity coined by Rush Limbaugh. And perhaps it was too harsh and loaded.
But I'll stand by my point they're idiots, like the MRAs and other morons they argue with.
But I tend to argue (I studied under Post-Second Wave and Third Wave feminism), that the Internet Feminists are so firmly ego-tied that they literally worship the "Myth of Feminism," similar to how certain "Myths" were the foundations of Nazi and Marxist ideologies. They spout near-religious tenets and rabid idiocy that makes me wonder if it's a Cult of Personality rather than a movement (and I most assure you Feminism IS a movement, not a Party). Second Wave feminism brought up lots of points, and certainly lots of yelling, and helped to push through social changes that started with the First Wave. Then issues such as free expression, self-determined sexuality, and yep, pr0n, came along and shook Second Wave Feminism to pieces.
Third Wave feminism, is a lot more fragmented, but opened a can of worms about female sexuality that Second Wave feminists considered degrading and oppression, whereas several former Second Wave feminists began to ask question about self-determination, a woman's right to her own sexual expression and determination that lead to a split. But I consider Third Wave's greatest achievement was the "recognition of the self" as opposed to a lot of Second Wave organizations that tended to lean towards group think. There are 3rd Wave Feminists who actually find Pr0n empowering, while others get involved in artwork that deals with female erotica and touching things the Second Wave would shriek at like a bunch of stuttering hens.
There's a clear difference when a counter-organization finally recognizes the need for women to start changing the culture, i.e. Fine Young Capitalists, and they've been getting some **** from the Twitteristsa and Tumlbrinas for actually trying to do something.
It's an outdated, ill-informed, and often dumb idea to attempt to demand culture to change without actually doing anything, and even neglecting to speak from a woman's perspective. Let's take the Feminist Art for example, I use Judy Chicago as an important goal-post, because hell, she actually did something, and rather than complain, she actually tried to speak and celebrate the idea, the notion, of women. A lot of Feminist Art was driven less by the need to "criticize" the Patriarchy and more to speak to the audience about a woman's world. And frankly a lot of Feminist artists are UNDER fire by Feminists for not appealing to set base of ideas, the problem rooted back to Feminism being a loosely affiliated movement instead of a centralized organization.
There's no central tenets to Feminism aside from striving for gender equality and women's enfranchisement.
Frankly, those are so much more powerful than a women squawking about "Gamers being misogynist,"
Women making games, comics, and other things, plus getting those works recognized and sold, would be more successful, and I dare say, intimate to the audience, than trying to force the AAA games industry to shill out to meet "Politically Correct" goals. Plus with the Internet crowd sounding like they came several decades behind the curve, it leads me to challenge their actual legitimacy to understanding what is Feminism.
Edit: I should clarify there's a distinct difference between Post-Second Wave and Third Wave feminists. Post-Second Wave feminists still maintain a strong connection to the fireworks of the Second Wave movement, but the Third Wave feminists actually "evolved" with the times and began to ask new questions, and gasp, worry less about the Patriarchy, and work on more personal and intimate levels.
