Edit: Is this a letter or some sort of opinion bit? Too long for letter, too short for opinion, IMO.
It's a bit muddled at the top to try and close with a rather trite statement. Unless your copy somehow furthers the issue at hand, keep irrelevant information limited and focus directly on your point. Especially if it's going to newspapers/magazines - they'll scan for about 10 seconds (as I just did) and quickly decide whether to hit delete.
I would whittle down graf 2, and mash together 3, 4 and 5 and clarify. Drop the kicker - b/c it doesn't really kick.
Sorry, tough day at work here. When I'm in the editing mode, it sticks for a while.
