Grade my essay please?

Your essay is not expository enough. You have to strengthen your claims, provide examples. To me it reads rather like a report than an essay. Remember: "essay" comes from the French word "essayer", to attempt. What were you trying to attempt here? Try to make it more enlightening instead of using the same tired phrases. Do not enumerate facts, but explain their import, and cite your references. Your grammar is also dodgy. The phrase "theoretical, iconoclast, or impractical" should be "theoretical, iconoclastic or impractical"; "sufferings, poverty, bigotry, and biasness" should be "sufferings, poverty, bigotry, and bias";"we should instead critically ysis" must be "we should instead critically yze". Adjectives go before nouns, adverbs modify verbs, adjectives, or other adverbs. Another flaw in your essay is the use of colorless, corporate words. Examples are: vital concept, best interest, develop and go forward, etc. (Read the book-length essay "Gobbledygook", by Don Watson, if you can. It is very funny and astute. )Other than that I think you do have a point; you only need to emphasize it. An essay should be able to make a firm stand. Just a bit more polishing ought to do the trick. Best of luck!
