World Football (Soccer to us Aussies)

Every time I watch a match I have consternation running through my mind.
During the game what is the thing that stands out the most?
Players and spectators yelling -"Ref.....Ref....Ref"
Shut up and let the Ref ref the game. Don't like it? Take up the task yourself, become a Ref.

Offside - Seems to me that this rule penalises the attacking side too much.
Supposedly in place to stop sides pumping the ball into a crowded goal square. Still seems to me that it overly penalises the attacking side.

Players diving - trying to elicit a free kick. Not in the spirit of the game. If you got to dive to get a kick, get off the ground.

Players feigning injury. So many players squeal out in "Pain" only to get up with nothing wrong with them.
Trying to dupe the Ref, get real you posers.
