I think that is a big part of the problem. They need to quit calling them the "ladies" and "senior" tees. Of course, that is well ingrained in the culture and it will be real hard to change it.
I believe what would also help is for better golfers to play alongside those who should use shorter tees. It would eliminate the stigma from hearing "I'm going to play from back here, but you need to move forward".
They call the white tees the "standard men's tees" and the blue tees "Championship" or "Back" tees.
If you drive straight and about 200 yards, it probably doesn't make too much difference which tees you play.
This is exactly where the problem lies.
Aside from older folks, pretty much any able bodied young to middle aged man should be able to play from the white's. Problem is with guys who have delusions that they should be playing from the blue/black tees and have no business doing so.
How about this idea ... say an average white length is 6100 yards, put the blue tee's at 6200 (instead of 6600), and keep the tips at 6800+ or whatever for the select few that should be back there. Making the blues and whites fairly close together would solve the problem by giving those who feel they need an ego boost, a realistic chance at playing the blues and not slowing everybody else down ...
That's not too bad of an idea, but 6200 yard tees is still too far back, 5500 yards would be more suitable for most people. It would make the game really fun and really fast, but many men will still play the 6800+ tees because no one wants to be "short".
Personally, I like the shorter tees, but because my playing partners and my son need to play the blue tees for practice. We are normally waiting for other parties anyway, so I'm not bothered by that.
If I am playing on my own, I pick whatever tees I feel like and stick with them.
