I like to tell jokes about things that I've experienced.  That is why I tell child rape jokes
Are you ok with talking about it?
No, I was traumatized by a priest and now I tell child rape jokes and vote for Trump.
Since you were the victim of trauma, you can probably empathize with other people who suffered as you did.  Telling jokes may be a way for you to deal with your emotional distress, but recognize that it can make the problem worse for people who hear these remarks.  If you need someone to talk to, there are professionals who are willing to listen and help.
