How should i start my persuasive essay on romeo and juliet

you should start it with an opinion. for example : Romeo and Juliet was the most tragic love story in history. (or if you disagree) Romeo and Juliet was the most simpleminded story ever! after that you should use some evidents to back up your claim. basic reasons why you think what you think. I hope i helped <3 (writing is sumthin dats simple for me lemme kno if u need anymore help)

When constructing a persuasive/argumentative essay, what you'll basically be doing it presenting your point of view on a certain element within the play then defending it with three points.  A good thesis sentence might include an opposing viewpoint and sound something like this:  

Even though some might say that the love Romeo and Juliet had for each other was immature, (Reason #1), (Reason #2), and (Reason #3) prove otherwise.

Remember that the points/reasons within the thesis sentence will be the topics of the body paragraphs in the exact order they will appear within the paper.
