Obviously, this doesn't make them kaafirs, but the level of misguidance is truly astonishing. Cursing Mu'awiya is as normal to them as drinking water. It's hard not to dislike them as a group for their actions.
Can't tell me this is caadi behaviour
May God curse Abu Sufyan, his son Muawiyah, and his grandson Yazid. May God curse them all.

Sunni stance on Yazeed
Yazeed is one of those whom we neither curse nor love. There are others like him among the khaleefahs of the two states (Umawi/Umayyad and ‘Abbaasi/Abbasid) and the governors of various regions, indeed there were some among them who were worse than him. But the issue in the case of Yazeed is that he was came to power forty-nine years after the death of the Prophet SAWS (peace and blessings of Allaah be upon him); it was still close to the time of the Prophet and some of the Sahaabah were still alive such as Ibn ‘Umar who was more entitled to the position than him or his father or his grandfather.
