DH and Interleague Play

Let's just say I'm not the biggest fan of the designated hitter.  I think it's a stupid rule and should be taken out of baseball.  What other team sport besides baseball allows you to field a player who either through playing the game and becoming broken down, drug abuse that broke down your body, or just due to your inability to be anything more than a one tool player, allows you to use you're only tool and not go through the task that every other player on your team goes through on a daily basis. 

Furthermore, inter-league play takes the DH and makes the series between the American League and National League teams unfair while being played on an American League field.  National League teams are built around have 8 solid defensive and offensive players and a pitcher to field a team where the American League is built around having 8 solid defensive and offensive players, a pitcher, and a one tool player who can only hit.  When inter-league play is played in an American League park it puts the National League team at a huge disadvantage.  When the National League team plays under American League rules, the National League team fields their normal 8 players, and then instead of batting a pitcher, they bat a normal bench player; someone who doesn't produce well enough to be an everyday player.  The American League team does the same, only instead of batting a bench player instead of the pitcher, they bat their normal DH hitter; someone who is paid solely to hit the ball.  How many National League teams have a Jason Giambi, David Ortiz or Jim Thome sitting on the bench to DH for them?  They don't play the field, they don't go through the 160+ game season going through the same wear and tear as your every day player..  They just bat.  They go out for 4+ at bats a game and sit on their tail for the rest of the game.  You wonder why the American League wins the World Series more often, why they are dominate in the inter-league play...  That one extra above average batter makes a huge difference...
