There are 2 ways to Eradicate Slutiness from the Female Race

1. Remove them from society entirely. They never have any interaction with males, ever. They do dirty work in internment camps, and are artificially inseminated.
2. Remove them from society temporarily, until they are ready for an arranged marriage. During this time, they are constantly belittled and mentally abused to the point where they have no self esteem. Then, they will not have the courage or confidence to whore around.

Excellent ideas. Most of us incels would probably prefer the 2nd option because we get a wife, but maybe the first is more wise in the long run. The government will have to fund research to create artificial waifus for us in that case.
