When someone was a pedophile and a warlord there should be no harm in stating the facts.
If people have issue with the facts it is not your problem it is their problem.
That's what I personally believe! But I have mixed feeling when I see people
mocking Jesus too much and ignoring other prophets like Mohammed (normally because they are afraid) or they
mock Catholics a lot when (in my country at least) they are extremely peaceful and tolerant people. I kinda wish they could take it easy and look for other religion faults too.
Mocking any public or fictional figure is just for fun.
I don't think Trump supporters would be offended when someone mocks his hair or his inability to use more than few adjectives (huge, great, good, bad etc).
Most famous people are mocked all the time.
You're right, sometimes I just worry they are picking on some personalities too much.
