You did read the post that you quoted, didn't you?Chairman Mao served for a long period. Didn't mean he was great? (he wasn't for the record, but I see similarities between him and Dev, the auld agri business and dancing at the crossroads type of mentality of a small minded elder man). Is that what you view as 'greatness' . I'd suggest you look up what greatness actually means.
You ask me to look up a word that I never posted!
No rush, thanks.
