5. I don't think the majority of the people getting deeply involved in this thing *on either side* believe or care about their own side of it much if at all. It's about 90% celebrities "taking a stand" (Wheaton, Day, etc) on one side and 4Chan trolls doing stuff just "for the lulz" on the other. Which isn't to say that the latter aren't dangerous. They've run young girls and their families out of their homes and into hiding before "for the lulz".
I do see how one could see it like that.
I would ask you to take a deeper look too; to the time before recognizable 'names' began adding theirs. Before it became multiple issues joining, sometimes having reasons that pushed them together.
This is an issue of status quo being challenged and pushing back.
In this case, and growing for a long time now, in gaming for this particular issue, is one gender speaking up about the increasing use in games as being acceptable that their gender is portrayed as disposable and abusable. (don't think that is a word but you get what I'm saying)
Increasingly this abuse is rewarded with points, scores, and with merely free form abuse, violation, mutilation, and killing.
And a growing segment of this gender began saying WTF?! This is not only offensive but it is wrong.
At the same time this gender was growing within the gaming ranks that was overwhelmingly populated by the other gender so the status quo was being challenged there too. There was gender marginalization going on from a percentage of the monopoly gender. (that wasn't a good sentence but you can get my drift)
Status quo challenges are age old and the challenged & challengers have often used some form of angry push back, sometimes even violence. Status quo challenges have been seen in religious ideology, civil rights ideology of races, genders. Genders moving into a field previously held by another gender, the world is flat/the world is round, the Earth is the center of the universe/nuh uh, medicine, science, political ideology, and many many other major and minor things not necessary to this discussion.
Now back to the status quo games issues.
We now have the Internet and anonymity that can be used as a weapon. This is HUGE. A shift in the dynamics of weaponry that can be used in a status quo challenge. And a segment of the gender of the status quo has begun using it. Then organizing and using it.
And the overwhelmingly focused recipients of this weaponry is the gender challenging the status quo. And the weaponry is using VISCOUS AND UNRELENTING attack methods of hate, emotional abuse, harassment, fear tactics, violation of civil rights, etc. Most often with impunity because of technology. Which is feeding it to continue and grow and frenzy.
The issue has evolved from one gender challenging the status quo... into viscous, unrelenting, cruel, illegal acts that are indefensible abuse.
This has now gone on long enough that 'persons' both everyday and celebrity are now involved.
And I can grant your point that a segment of people are
"people getting deeply involved in this thing *on either side* believe or care about their own side of it much if at all." That it carries sway for some to align with 'celebrity' because of celebrity.
And I can grant you point that a segment of people ARE the
"4Chan trolls doing stuff just "for the lulz".
Though I suggest to you that your '90%' numbers do not approach accuracy, and I encourage you to look deeper into this issue to see if you yourself continue to support this number assessment as an accurate representation.
