Political humour by its subject matter is about ridiculing groups or individuals for their thinking and behaviour in some way... depending on which side one sits on. If one is going to engage in it, be fair to everyone and piss-take them too... 'equality', see.
Everyone has their 'taboo' subjects' and 8 Billion variations is too many to accommodate, so if you want to do it, do everyone. If people are offended by mistermack's post, I nuked the neg, then maybe they best stat away from political jokes because attacks their collective behaviour and not their being,which would be personal. Attack the behviour, not the person.
