I'm sorry if this disturbs you but free humour is one of the extremely important aspects of the internet that Lemmy needs to support. When you know who you are talking to you can avoid subjects that may hurt the other person but on the public internet this is not possible. The alternative to never dare making any joke because of the risk to hurt someone is dystopian.
Top comment isn't even a joke, it's a movie reference that supports the idea that this is a serious topic.
