Sentence: "The reason I am writing this post because I want to tell the people, who think he is a crook , to not make perception under pressure from liberals, conservatives or on the reports of corrupt media. Just be a contrarian for a while in this case."
My question: Is the preposition to been used correctly in the sentence ? Second question is the word under pressure been used correctly in the sentence ? And if there are other errors in the sentence then do point it out them also.
