Irongrampa whoopin on a flag-burner
I believe if you bought yourself a flag, you can do whatever you like with it on your own property.
Or so I might argue, purely from idealism of liberty, any other day of the year.
But that said, I might be slow to phone for help if, say, I saw irongrampa whoopin on a flag-burner. Sometimes I just can't remember the number for 9-1-1, y'know.
