Taoism's confusion with the Bolsheviks (7)
I believe the answer is:
maoists
'the bolsheviks' is the definition.
(both are types of communist)
'taoism's confusion' is the wordplay.
'confusion' indicates an anagram.
'taoisms' is an anagram of 'MAOISTS'.
'with' is the link.
(Other definitions for maoists that I've seen before include "Followers of Chinese leader Tse-Tung" , "group for a Chairman" , "Followers of China's revolutionary leader, d. 1976" .)
