Expressing your patriotism with a lapel pin or a yard sign is fine.
Expressing your patriotism by attending a rally or sending cookies to the troops is fine.
Expressing your patriotism by knocking on a strangers door and lecturing her is *not* fine. She has (last I checked) the right to display her opinion in a non-inflammatory was on her own property without fear of harassment by strangers.

........without fear of harassment by strangers.

Guess again. What law says you can't knock on someones door and tell them you think they're a jerk? If he went over the line he'd be in jail. He's NOT in jail. His only mistake was in wearing a company logo while doing it.
