Nearly everyone in my family served in the military; I had an aunt working in the Pentagon and an uncle who served in the Middle East during both gulf wars; my stepdad was a marine my grandpa was a Korean war vet (and my gran got with a WW2/Okinawa vet after his death). I tried to enlist as well, but asthma prevented me.
I asked my uncle how he felt about people being disrespectful to soldiers - you know, the whole protest and baby-killer slurs and skaters using war memorials as a skate park sort of thing. Nearly every soldier I've ever met gets really pissy about these things and think people should be punished, but my uncle just calmly shrugged and said that he's basically out there fighting to give them the freedom to be able to be twats and say abusive towards him and use his monuments as a playground.
True fucking hero, there. Even though my blood boils in the presence of twats like this, I just follow his example and ignore them, instead choosing to find the silver lining in their stupidity by being thankful they even have the freedom to be boorish cunts. This is a helluva great country, and it's all thanks to the soldiers who made it possible.
It happens across the country, but then one of these thieving scum has their skull blown off partially while trying to steal metal wiring from a train line and we're supposed to feel sympathy towards them
Petition the city council to designate a proper zone for the idiots. Its what I'd do, put them off in a skatepen with a policeman or patrol car nearby. Of course upon arrest, I'd have the delinquents dragged before their parents.
