In MN, the long tees are designed as the proper tees and short tees are there to facilitate youth/eldery/female/otherwise handicapped players. I understand that other parts of the country have less capable course designers, where the "long" tees are simply slapped on with added distance to accommodate the extremely small percentage of players in that area that can break 350'. Here in MN the short tees are slapped on to artificially take off distance and difficulty for the minority of players that suck.
This isn't weightlifting. You cannot hurt yourself by throwing from a more challenging tee. And there is simply no benefit to playing tees according to your ability level. If you are not a mental midget you will be able to cope with the higher scores, and at the same time aspire to throw a disc properly and proficiently enough to eventually score well from the longs.
Evidence that my snobbery is warranted:
