This is a rather tricky topic to write about. I'm not sure why a learning institution would like to know a particular political stance that you have (especially when that stance is most likely similar to that of others.. who doesn't support freedom of expression?).
I feel like there might a right way to answer this question. The learning institution may be looking to see that your beliefs align with theirs. Perhaps you could research the university in order to locate content that should exist in a superior answer.
While I thoroughly dislike the question, there are a few ways in which you can improve your existing essay.
Note that the prompt requests examples. I see no specific examples in your essay - you only included personal commentary.
Some work forms are so erratic in their content that they have potential to spark a revolution in a society. In these cases, government intervention may be essential to maintain the stability in the social infrastructure of the country.
I personally do not find that argument valid. You seem to be supporting a government's suppression of revolutionary ideas.
To recapitulate, expression of one's belief should not be refrained. Allow the people of the society itself to decide whether they agree or disagree with the content. Therefore, government should exercise minimal control over the art forms as they could be a good reflection of the people's belief.
Thesaurus overload! Recapitulate means "surrender again" and refrained is a verb - you are using it is a noun. Just put this last paragraph into plain, intelligent English. Let your content, not your superfluous wording, make you look intelligent.
I feel bad for you. The essay prompt is rough. Make sure to give examples through a well-structured, strongly opinionated essay.
Good luck! If you have any additional information to share, or if you have revised your essay, please re-post it!
