there is a video on youtube where Kahane is giving a speech, and somebody comes onto the stage. Kahane pushes him. The guy was shocked..
There is another video of kahane in skokie, where he challenges neo nazis to come out.. and he calls them out as cowards.
kahanists also challenged the black panthers.
Kahane used to go into arab towns .. I don`t know how he protected himself.
He was attacked by israeli intelligence officers once, when alone. They tried to put a bag over his head. He dropped to the floor , and they couldn`t do it. So they hit him with batons to the head.. He covered his head.. so they hit his hand/arm.. He shouted out "TERRORISTS" (perhaps he thought it was. But either way it was effective).. They ran off.
He was from the streets of brooklyn. I don`t know what the mentality is over there.. But he seemed to absord alot from that brooklyn background.
Your question would be a great one to ask Chaim, in an askjtf show.
