I don't believe that bullying is actually to blame. Speaking as someone who has been through it and damaged by it, I can say that for my part, the damage that has been done, is damage that I allowed to happen because I was never taught to stand up for myself--in other words, how not to be a victim. This problem will continue to get worse as our culture drifts away from individual empowerment and toward institutional protection, unhealthy coddling and self-victimization.
You see the latter demonstrated in the absolute extreme in the online community of Tumblr. Thousands of ordinary men pretend to be transsexual or schizoid in order to tap into the kind of sympathy that girls receive in our culture. They pick the most extreme conditions, then complain about every possible thing as some kind of discrimination. They talk of nothing except how oppressed they are, because they have not been taught to assert themselves as men.
Even girls are suffering from this as feminists constantly shame us for what they call "blaming the victim." If you try teaching a girl how to avoid being a repeat victim, you're just blaming the victim. So girls get the impression that they shouldn't have to be responsible for their own safety, and we see them stumbling around blind drunk at 3:00 a.m. completely alone. Many is the time I have walked a girl home or called a cab, but that should not be necessary because they should have been taught better sense than that.
We will never be able to teach criminals not to be criminals, but we absolutely can teach people how not to be victims, and how to proceed through life with assertiveness and confidence, and personal accountability. We can start teaching our children once again how to earn respect, instead of manipulating others for pity, or allowing themselves to be dominated.
