....And as well know - the correct response is "Fuck off" - as demonstrated by some photos from the Trots assembly in Sheffield yesterday.
Witness this woman, covering all her leftie bases with a "No to Isreali Defence Force, No To Hamas" banner (with it's other side blathering something about solidarity with women & comrades). This seemingly level headed approach seemed out of touch with some at the march, with them taking offence at being against agression on both sides.
Thus we have this man (complete with megaphone for slogan shouting)
In the last image - notice the man with the brown coat in the foreground? He now decides to get involved
Isn't it fun when comrades fall out?
