The protest document is urging readers to assert their opposition to the draft.
It views conscription (forced enrollment in the military) as a transgression of the citizens' rights protected by the Constitution. That is why the document asks people to resist the draft ("Do not submit to intimidation") because if they consent, they are also part of the problem. Submitting and being silent about their rights would mean that they are encouraging freedom violation: "If you do not assert and support your rights, you are helping to deny or disparage rights."
A run-on sentence. "A triangle is a polygon. It has three sides."
My advice is to just be yourself but lie a little bit
The Tragedy of Julius Caesar deals with the themes of fate, betrayal, and honor, among others. The chief conflict of the play centers on the conspirators' hatred of Julius Caesar's increasing power, which could lead to his becoming king and to the dissolution of the Republic. This tension is about power, one of the play's themes. Also, the men who will assassinate Caesar are his friends, and the play explores the limits of that bond as it is tested by ambition and power.
