Earlier quoted context omitted.
I'm not in the USA, but I think the issue is not so much the joke getting tiresome, but the repeat school shootings. Maybe if there was work done to stop the shootings, then the joke wouldn't keep getting repeated.
First and foremost you should attempt to be funny or original. This is neither. It's political. I would love headlines like: > Illegal Immigrant Finally Caught After 20 Years of Successfully Contributing to Society but instead you get non joke headlines like: > ICE Agents Hurl Pregnant Immigrant Over Mexican Border To Prevent Birth On U.S. Soil It's just cringe.
Who are you to declare what satire and and cannot criticize?
