From an anti-authoritarian standpoint we always engage in critique of established hierarchical models. Sometimes, depending on a method, this critique might be perceived as hurting someone's feelings (religious and not). Sometimes it can even looks like purposefully being an asshole.
I want to discuss, when it is acceptable to hurt someone's feelings? I suppose, the easiest answer "punch up, not down" applies here. But, the truth is "up" and "down" are very subjective things. It may lead to classical tankie's response "don't criticize China from your imperial core". Could it be extrapolated to "don't draw caricatures to the Prophet from France"?
There, probably no clear answers and guidelines how to always punch "up" without collateral damage to "down", but, anyway, I would appreciate your opinions in comments.
