Reality is scarier than fiction for a ten-year-old gay kid in small town Indiana in 1982. Based on actual events, one boy’s journey of self-discovery comes to a halt when he hears about a gay cancer that is merely foreshadowing the ignorance, fear, hate and religion that almost ends his life and forever changes his world.

You should write the logline from the point of view of the lead character, not a narrator.
-----
"When he hears about gay cancer, a small town, ten-year-old?must..." (I am not sure what the lead character's goal is so it is hard to move forward)

What is the lead character's pro-active goal
What is standing in the way (Is there a specific bully, for instance?)

It's certainly a plus if yours is based on actual events. However, you must be specific about the detail that encompass his conflict. How does it go from "his journey of self-discovery coming to a halt.." to "..almost ending his life"?
"when he hears about gay cancer.." is your Inciting Incident, right? How does that fling him into ignorance, fear, hate and religion; which has such a wide possibility of plot, suggesting anything can happen...
What becomes his Objective GOAL a result of the Inciting Incident? What is the nature of action must he take to achieve this specific Goal?

Where is your plot headed??

Think in terms of a starting point and an end point.
