In much the same way we don't in civilized society accept racism, homophobia etc. We shouldn't tolerate bullying.
It's like having a leak in your roof, you can throw a bucket under there and call it a day, but you haven't solved the problem until you deal with it at the source.
I have experienced very similar bullying to
@Shamar . It's all very well to give victims tools or skills that help them cope. But if the bully's intent is to keep ratcheting up the pressure until it overwhelms your defenses it's really just a bucket under a leaky roof that will stay that way until you deal with the problem.
I did very well one day when I was eleven years old with some bullies. I wasn't able to catch my school bus that day due to not having a pass that my mother refused to pay for. So I tried to get on the bus and was kicked off. So I walked home and was instructed to catch a normal service bus to my school 6 miles away.
When I arrived at the stop near to my school I got off the bus stressed that I would be in trouble for being late. I saw two young men on a bike approaching me, who began to harass me. I did as people advised and ignored them. They then started getting physical when I didn't respond. But I didn't rise to it.
Then as I approached the road opposite my school they blocked my path. I knew I couldn't outrun a bike. I tried to walk around them, but they moved in my way again. Then they began to move and I finally thought it was over. They circled back. One of them punched me viciously in the face, bursting my cheek open in two places due to the heavy sovereign ring he was wearing. I was bleeding heavily and still had about half a mile to walk to the school building. I had concussion and I was in quite a lot of shock.
So there you are. Keeping quiet and not rising to it works great. Oh actually wait. No. That's total utter self indulgent crap!
