This is true of gamers are well.
Either the extreme parts of the group, aren't actually a part of the group or they are. You can't say "bad actors have tainted feminism" while arguing against that statement for something else.
As I just wrote, this is the problem with any broad label.
That is true. It's a difficult to understand and complex subject. One of the first similar examples that comes to mind is racism. Within the mind of a racist, bad examples within the black community or high crime statistics reaffirm their belief that there is something inherently wrong with black people. This creates a kind of self-fulfilling prophecy, where racists view and treat black people extremely poorly, over time causing the black community as a whole to both fall into poverty (and sometimes crime) and be searched and arrested all the time because of people's suspicions, which to them then reaffirms their inherently wrong beliefs.
Within feminism I believe a similar thing is going on. You have a general movement that fights for equal political, economic, cultural, and social rights for women by being very active on a social and political level, trying to ensure that women have equal footing when it comes to employment, health care, sexuality, reproductive rights, laws etc. This used to be a very cohesive movement that had a lot of success in getting us closer complete equality.
Since the 80's feminism has sort of branched off into various movements and standpoints, this mainly being a split between those who believe feminism has "achieved its goals", or post-feminists, and those who believe much more change is needed, some of those being standpoint feminists who want to address global issues and third-wave feminists who kick-started the sexual revolution (thank god for that), and then those movements intertwined with race-related movements etc.
This is the first problem. Because of all these branches, whenever someone says "feminism" or "feminist" it can mean at least ten different things. This makes the conversation very difficult as many people assume that when they say "feminist" you know exactly what you mean.
Secondly there is the problem of the internet. Because of social media, extreme voices have a place to gather, shout, organize and fight. The loudest voices often tend to stand for the most extreme interpretations of feminism and I believe many of them actively scare people away from listening to some of their legitimate grievances. This causes people on the internet to perceive feminism as this aggressive, accusatory, generalizing movement that they feel they need to defend themselves against, which then causes those feminists go on counter-attacks and you end up with two sides that just continuously reaffirm their own misconstrued beliefs.
In the meantime calm, rational, intelligent feminist; who would much rather sit down with people and have intelligent conversations and debates, trying to forge alliances and work together, are over-shouted and painted with same same brush people use to paint these extreme feminist.
I think what it comes down to is that feminism needs to be revolutionized again. It needs to be redefined as a single "thing", that is clearly defined and easy to understand for everyone. Something all rational, intelligent human being can stand behind and root for. There needs to be a way to stop some of these extreme individuals from redefining what feminism is supposed to be, I mean we've reached a point now where it's not just feminists versus "men", but feminists versus feminists.
I see nothing of value coming out of this current "war" that's going on. Everyone is going to have to sit down, take a deep breath and calm the hell down. We're going to need intelligent, rational voices to take control of the discussion, have actual journalists do some actual investigative journalism and present factual, as-neutral-as-possible reports, and most importantly we need to start listening to each other. These endless 140 character rants and ravings on twitter accomplish nothing but more hatred. Even here on NeoGaf I see a lot of people that just need to relax and stop being so judgmental. You can't force change upon any group of people over night by going all out on the attack. Change takes time and it takes intelligent leaders.
