I find it interesting the polarity -
extreme criticism of (what is perceived as incorrect) ideology on the one hand, with the mental images of hectoring Maoists coming to mind,
and the opposite polarity of
complete self-annointing regarding one's own holier-than-thou position, which passes tick-boxes of certain key phrases - for example, it is acceptable to call Israel an example of 'settler-colonialism' but NOT acceptable to discuss Israel as showing many trends towards becoming a fascist police state.
