HELP! Struggling with planning for tomorrows essay

Here is a plan for an essay (covering all possibilities) - this is the way my brain works so it is following a bunch of lines and making connections between themes and setting.

If I was planning it out I would look at 

Intro: Outline themes and cover the basics of the Salem lifestyle/setting, as well as defining McCarthyism/what was happening in America in the 50s.

Paragraph 1: First aspect of Salem's setting (black and white courts) - relates to themes of inflexibility and irrationality (dangers of not being able to look at both sides of an arguement - being so strong in your belief that you are right and everything else is wrong) - explain this in relation to McCarthyism (similar court situation - either communism or not)

Paragraph 2: Second aspect of Salem's setting (superstition and unwillingness to bend) - relates to the theme of intolerance (intolerant of those who are different or question: questioning authority is a sign of evil/witchcraft) - explain how this relates to McCarthy trials (truely believed in communists regardless of the lack of evidence, those who questioned were black-listed, including Arthur Miller)

Conclusion: Summarise major points in P1 and P2.
