Personally, I say neither one is better or worse than the other and it should be taken on a case by case basis. From seeing the way this punching up/down concept often gets used it seems like a step towards the idea that you can do no wrong since you've declared yourself less privileged than your opponent, therefore, your attack is inherently more just.
If we're talking about comedy on the other hand, the same thing more or less applies. The purpose of comedy is to make people (of a certain comedic persuasion) laugh, not to be an arm of some political group. You can use your comedy for that purpose if you wish, but you should not expect anyone else to do so if they do not wish.
