Hazrat Hussain was a sahabi (though few muhiddisin consider him a taabi coz he was a child during the life of hazrat muhmammad ) beside he was a grandson of prophet. and thats why me and all muslim love him. A pious and learned personality.
but he was not imam (its my and sunni point of view).
CONCLUSION: You have no real knowledge of the Quran, Hadith, and the views of the classic sunni scholars on this topic. Therefore its a waste of a time discussing this with you. Specially when in the past you have opened many controversial topics only to be disappear once confronted and corrected.
