I would have to disagree....too many bad things are happening in our world right now that aren't funny at all.
No there are some topics no matter how ya spin just ain't funny
Humor can be found in anything...sometimes as a coping mechanism. Those who deal with horrible deaths regularly, for example, such as homicide detectives or medical examiners, may make light of things that would horrify most of us. I don't see that as being disrespectful, but as a way for them to maintain their sanity while being inundated with insanity. So yes, though there are things I could never find humor in, I can understand those who may.
What is funny is entirely subjective. No one has the authority to decide what kind of natural human emotion is correct for the entire world.
It really depends on one's frame of mind at the time.
If one person finds humour in something I don't, then so what?
Pedophilia, Abuse, Neglect, Torture, Slavery. Cruelty. Evil. Those things are never ever funny. If they are then something is very wrong with you.
