We do take what we dish all the time, what we pretty much never dish is public and directed attacks on individuals (or other social attacks of which there are many, such as spreading rumors). If I'm in a room with someone that is continually spouting off about all men being sexist pigs and making period jokes I really don't care, that is their prerogative and I have no right to stop them much less publicly attack them (nor do I feel the need, but that is another issue altogether).
