I don't care if he keeps it up. He has the right to free speech in our country.
That right does not make him any less rude Kel. Because he is being very rude and if I was his neighbor, I'd be just as irritated. He's being tacky and rude and his yard looks ugly. I'd feel the same kind of irritation if a neighbor didn't mow their lawn for three months.
However, once again, he has the right to have a tacky, rude display in his yard.
