the fact that you'd make that comparison is, I think, extremely telling.
Could one not argue that it is telling us that there is a need for such organisations, and that the privileged mainstream prefers not to address such issues, because it would have to give up on some privileges?As an aside, what is the reason that you mention the suffrage without mentioning that the suffrage movement did not campaign for women being included in the draft, when the only non-sexist resolution of the conundrum would have been (and still is) to legislate that suffrage should be given exactly to those who are subject to the draft? In other words, why did you omit mentioning this outrageous and still ongoing basic sexism of the suffrage movement?
Clearly men did and do not have the ability to vote in a large amount of political climates both historically and currently.
This isn't a gender study class. The fact that someone's opinion is "extremely telling" means they are getting their point across, and as much as you would enjoy that to be a GOTCHA, it's not, and you won't be burning anyone at the stake here.
But more generally, what happens on Wikipedia is that a few passionate and experienced editors with an ideological motive (who have unbelieveable amounts of time on their hands) begin "taking ownership" over a collection of pages. (Some of them even organize "edit-a-thons" with other activists in a team effort to quickly skew a page.) Once the page has become biased, progress to fix it stalls to a standstill because they will fight every change tooth and nail, and because they can dogpile to create the appearance of a consensus in the talk page, they succeed. The other side has equally as many people disagreeing with their stances, but they are not hitting the article all at once in an organized stance so they get picked off one by one.
Without a degree in wiki-lawyering, a team of dedicated editors by your side, moderators who will do your bidding and the equivalent of a semesters worth of free time available to contradict attempts to overemphasize one POV, you don't stand a chance.
It is pointless to try to compare movements this way as there is always an other movement that is bigger and older.
