In manners such as these, considering intent is important.
The radicals who burn the American flag are protected by the 1A. Yet they have evil intent. As you noted 4Runner, their actions are disrespectful to those who died for that flag.
But what about the flag on shoes (and clothing). Some are doing that just to make a fashion statement. That’s not evil, just in poor taste. But I’m guessing most of them are patriots in their own way. Good intentions there.

But I suppose autocorrect had a point there. Manners plays a part, too.
