If you don’t show respect (i.e. concrete support and help) for a madman, you are Hitler:
You can destroy the whole world like this:
Crazy people are so disrespected that your “little” disrespect may be enough for a chain reaction of disrespect for this person through all the world. If the disrespected by coincidence turned out to be a great scientist (maybe even without a degree: he is not respected) or an inventor, civilization may come to an end: stupid people begin to disrespect his invention – and this is the end (slowly rotten mankind), because the system will lack a tiny, but important component.
Conclusion: those who do not respect crazy people are dangerous contagious mental patients (“Hitlers”).
Another conclusion: crazy and freaks should be respected more than others: pay them compensation for the fact that your brothers do not respect them: resist Hitler (if you do not resist Hitler – you are a non-Jews :-)). So, crazy people are the most important members of society.
