Should you go to "battle" for an injustice that only causes you a minor inconvenience?

Let’s say you are walking down a sidewalk that is being patrolled by a spelling fanatic. You come walking along, and the fanatic tells you that you may not walk down this half of the sidewalk, but you may walk down the other half. This is because you mispelled a word.

This is, you believe, unfair, because the sidewalk belongs to everyone. But all you have to do is take one step to the side, and you can be on your way.

Would you go to battle and try to somehow get the spelling patrol person out of your way, or would you just step to the side and continue? Why?

If a friend was in the same situation, would you advise that friend to take on the patrol person, or to step to the side and go on his or her way? Why?

If you were the sidewalk sweeper and a confrontation between the patrol person and the bad speller kept you from doing your job, would you tell the walker to step aside, because it is only a little thing? Why?
