Consider this:
"They" will succeed by controlling education and public attitude via the MSM and the entertainment industry. As results allow they will simply conduct a soft change.
The 2dA will not be in play; it will become as out of vogue as high school gun clubs. There will be armed resistance, of course, in isolated instances so relatively brief and futile as to be insignificant in the larger scheme.
I am truly an optimist, but have read and seen enough of history to give odds on it.
High School Gun Clubs would be great to back. Here is a sport real girls and boys can compete against each other in, without worrying the sexually confused having a physical advantage. Bring back guns and girls sports in one swoop.
