I think that you miss the difference, here.

While some antis exist like you describe, my point was that all of the online anti hate groups of the PJ, blogger, et al groups are nothing like that. They have no morals beyond what they can use to attack others, they have no interest in protecting children from actual harm, only in spreading disinformation and committing hate crimes when possible. The people that you are hoping to reach are people who have no conscience and are hypocritical to the core of their being.
