I see two subjects here (not necessarily related) -- helping out other bowlers, and the fairness of handicap.
The helping out question is easy. Regardless of our respective abilities, we can all use some level of help. It doesn't matter if you're a beginner or if you compete in high end scratch leagues. Being friendly and showing a willingness to give input (as well as receive it) goes a long ways in making the sport fun for all.
Handicap is more complex, but in most cases, the facts are clear; high handicap favors the lower average bowler. There is little to dispute, and a simple example of 100% of 220 handicap illustrates this.
Bowler "A" = 120 average (100 pins handicap)
Bowler "B" = 220 average (0 pins handicap).
If both bowlers bowl their average, we have a tie, and consequently a "fair" situation. However, life is not that simple. The reality is that it's much easier for "A" at 120 to shoot significantly over average than it is for "B" at 220. All the 120 average bowler has to do is pick up two additional easy spares in a game to take their score to 140. That's not too tough to learn how to do over the course of a league season.
It's much more difficult for the 220 average bowler to score a 240 and stay even. He/She have probably been bowling for years, and there is little room for additional improvement.
Forgive Joe for struggling with this, but it's a concept he has yet to grasp. He thinks in the narrow view of Senior leagues where there is some merit to 100% handicap. In just about every other setting, it's badly flawed.
