Here’s the plan, go to walmart and by an American flag kit. Sneak over about midnight and hang it on the side of his garage. In the morning call the HOA and tell them there is an offensive, racist symbol on flag pole next door. They will come right over and the see the mess for themselves.
Holy crap, I just about spit my Iced Tea on my laptop. That would probably work.
Or buy a Confederate flag and hang it on THEIR garage. Take a pic and put it on Facebook, whole place’ll be gone in a few hours.
