Child molestation, animals and women being abused are serious issues and I've not seen one person make light of those topics.
In my case, I use humor to help me get through the stresses of life that we are all under, it's mostly just tongue in cheek.
The world is harsh and PCOM is a great distraction for a lot of us. Look at it from that perspective and you wont be nearly as offended.
You don't have to go away. Just lighten up, I mean that in the kindest way possible.
