Okay kiddo, have you ever heard of the word "gay"? It means when someone is attracted to someone of the same gender rather than the opposite gender. And a community means a group of people who have something in common, like living in the same area or liking the same things.
So, the "gay community" refers to a group of people who identify as gay and live in Boston. They might have events or places they like to go to hang out with other gay people or support each other.
"Gay community news" just means news that is specifically about the gay community in Boston. It might be about events they're having, new laws that affect them, or stories about people in the community.
Basically, it's just like any other news, but it's talking about a specific group of people who identify as gay and live in Boston.
