Is this sentence correct grammatically?
Artists are other than politicians played their own roles of cultural critics.
I found it here and I think it should be transliterated incorrectly.
I can't find a way to parse this sentence, even by adding commas in various places. As far as I can see it is not grammatical.
What is the subjects of played? Why do we have present tense are and past played?
Artists are other than politicians
makes some kind of sense in isolation. Either of
Artists played their own roles of cultural critics
Politicians played their own roles of cultural critics
would also make sense, but running the two together does not work, we don't know the subject of played. We could use who to clarify that we mean politicians.
Artists have a different nature from politicians, who played their own roles of cultural critics.
But I would rewrite the sentence, pulling out the separate parts of the argument:
One of the roles of an artist is be a critic of culture. This may have some similarity with the actions of politicians, but artists are other than politicians. Politicians play their own roles of cultural critics.
