The world is not black and white and simple. Things could be taken out of context, and people tend to project.

People have got into trouble for having retold a controversial joke that they had heard, when the reason they retold had been because they themselves had been upset about it.

I too don't think that holocaust jokes should be accepted, but sometimes people say things because they don't know better at the time. There have been cases of people retelling "dog whistles" without having understood their contextual meaning for certain groups. I've even seen politicians use the phrase "Works sets you free" without understanding why it is inappropriate. People learn and change, but old posts can linger on the Internet for a long time.
