Why Yazeed Is Not Sunni Caliph & R.A.?

I was just wondering about this question that Why Yazeed (l.a) is not respected by many Sunnis and they do not like him. The only answer i got is that the predecessors of Yazeed (L.a) were smart enough to work with hypocracy and Munafiqat. They were enemies of Ahl ul bait (a.s) but they kept limit of their enmity and kept on working on their agendas secretly. Abu Bakar and Umer usurped Fadak and also made a hadith to justify this oppression. They usurped Khilafah from Ahl ul bait (a.s) and caused pain and agony to Hazrat Fatima a.s but still they managed to avoid full fledge war against Ahl ul Bait a.s therefore, in spite of their being wrong Sunnis to some extent justify their rule and respect them as their true caliph. When we come to Muawvia (l.a), he is also accepted as caliph by some of the Sunnis and they try to conceal his evil deeds and praise him because though he fought battle against Ali a.s but he did not personally caused damage to Ahlul bait a.s. He managed poison for Imam Hassan a.s but this act was concealed and he did not expose himself openly. Still he managed some space for defense for Sunnis but when it comes to Yazeed (l.a), he was open Fasiq and killed Imam Hussain a.s and all the family members of Prophet and also imprisoned Ahl ul bait a.s. Therefore, it became difficult for Sunnis to accept him as caliph. Otherwise, if Yazeed (l.a) would have been tactful like other Sunni leaders then in spite of his munafiqat and bad deeds he would also have been ranked as Sunni caliph but it looks that he was foolish and could not follow his predecessors in their tacts.

However, there are many Sunnis who still try to defend Yazeed (l.a) and convince people that he was from ahl e Jannat (Nauzbillah) because he fought battle of Qanstantunia and they are also annoyed when Sunnis do not accept this. Even those Sunnis who do not like Yazeed (l.a) say that we should not curse him because this may ultimately result into curse on some Sahaba. (lol).

To conclude, i want to say that:--

1. Sunnism is power worshipping faith and every one who gets power and authority then he becomes Oolul Amr for them and it becomes obligatory for them to follow him.

2. If a ruler or caliph is otherwise corrupt and bad in faith but apparently does some good work then it is hard for Sunnis to refuse his authority and his apparent acts are enough for them to follow him. This is Sunni history and i am not talking from fragments of my imagination. Here Yazeed made the mistake, he became open enemy of Ahl ul bait a.s and caused problem for Sunnis to follow him if he would not have done it openly like his predecessors then he would have got the same respect which Abu Bakar, Umer, Usman and Muawvia got.
