Defending Yazeed!!! Why?

I cannot understand why some people come forward to the rescue of a man like Yazeed. Recently I heard a story from one of my friend which cleared some of my thought in this regard.
A king was passing through a river mounted on a camel; suddenly camel turned to her kneels and sat down in the running waters. King was saved some how but he could found the reason behind the unusual behavior of his camel. When he made further enquiries he came to know that the mother to whom camel was born was an orphan. Soon after her birth she lost her mother and was brought up on the buffalo’s milk. Buffaloes have the tendency to sit in the water during summer and so did the camel. He was doing nothing wrong because in his veins run the blood of a camel with some imported genes of of a buffalo.
Yazeed and his descendants ruled over the Islamic kingdom for almost one hundred fifty years. Many of the people were employed under their tyrannical rule. It is said that the diet often transforms the human behavior. I can only say that the defenders of Yazeed are such people who are either infected with his blood or his bloody food.
Recently one of my friends defended Yazeed and said that he too was disturbed when he heard about the brutal murder of Imam Hussein (a.s). When I asked him; so why did he kept the Ahlul Baiit captive in his jails, he opposed me and denied the historical fact. Moreover he said that it may be a lie born among the Shiites. He had no answer when he was informed that the Daughter of Imam Hussein (a.s) still sleeps in one of such cell.
A whole stream is flowing around the world which comes everyday with new excuses to defend the tyrannical Satan.
Moreover these are the people who have nothing to do with Umayyads or Hashmiites. Many of these are neo-converts to Islam. Only one reason I could found is the camel-buffalo tale. Surely these people are brought up on the diet that is either illegal or belong to some tyrant. Otherwise these people have some blood of Yazeed in their body. Possibility cannot be denied because Yazeed and his family members were infamous for adultery and illegal sex relations with the women of their subjects.

There can be no excuse for a ruler. None of his employees should have dared to go an inch ahead of his order. Ibn Ziad was ordered to kill Imam Hussein. Shimr often claimed such to Ibn Ziad, Umar bin Saad etc. Moreover the atrocities met by the Ahlul Baiit on the way to Damascus and In the court of Yazeed require no further clarifications.
