I would first probably give them a glare until they say something to me and then they would probably hear my whole life story. Not to mention the freedoms they have because of our troops.

I would try my best to bite my tongue, but if it continued I would definitely have to say that those HEROES that they were cutting down were the very ones who fought and DIED to give her the freedom's that they so loved, and if they didn't appreciate that, then maybe they should move somewhere that those freedom's weren't given, and maybe they'd come to appreciate the brave men and women who sacrifice each day for them

I would let them know that bc of the Soldiers they have the Freedom to stand there and say what they are~
