Maybe try tantric Buddhism, one of the root tantric vows is not to be nice to enemies of the dharma and malevolent people, using force where necessary.
Since tantric vows are of a higher order, it's okay to break lower commands such as those given in the sutras. It's still important to get the guidance of one or multiple teachers to make sure you're not doing things wrong.

This is a based tidbit, I've dabbled in tantra and even own a few books but I didn't know that. Thanks anon, I will certainly be looking into this. I can definately see why ahimsa would be taught to the masses but with a different set of standards for tantric initiates.
