Standing or sitting?

I have always been baffled by 'toilet seat' battle of the sexes.

In the western movies it is such a huge deal if a man forgets to put the seats down after using the toilet. Nah, I am not on the men's side. I just cannot comprehend the issue. An issue (according to the numerous movies I see) is so huge that it can cause a crack in even the strongest relationship.

I would be more concerned if he did not raise the seat before peeing. I mean all of us know that men suck at hitting the target. Even with an area of 1 feet in diameter (and the aiming from distance of just half a feet away) many would fail thus the splash around the toilet rim or seat (if it's not up). What would irritate me is the inability of some species to just wash the seats/rim if that happens.

And what is the big deal in putting down the toilet seat? It only takes less than a second to do so. I mean if it's up put it down and if it's down just sit. It is not often that you'll go to the toilet in such urgency that you can't take that 0.5 second to put down the seat. And even if the seat is down, in such grave situation, I doubt you'll even have the time to remove your undies. Worse scenario, you will just pee a bit in your panties, and if a wet underwear grosses you out just remove it and walk around commando style. Such a liberating experience.
