I agree with some of what you are saying Racheal. For a good fast / medium bowler (i.e. Hoggard / Asif) with an oldish ball it can be a good attacking move to have the keper stood up. It will only be effective though IF the bowler hits the right length and he if moving the ball around (swing, seam or cut it doesnt matter). If the ball isnt moving that type of bowler is better off bowling more defensively and trying to "strangle" the batter out.
I also suspect that there is a bit of testosterone flowing through the veins of a lot of medium pacers and they dont want the keeper standing up to them, because to them its as if their manhood has been questioned. Personally speaking as a swing/seam bowler I love it if i can get a keeper who is good enough to stand up, at club level it pins batsmen on the back foot.

Regarding bouncers, if the bowler is genuinly quick and knows how to bowl a good bouncer (not many current test fast bowlers can) a bouncer is a wonderfully attacking weapon. The bowler has to know how and when to use it. The likes of Lillee, Roberts, Garner, Ambrose, Marshall and even Pollock in his younger days all had very good bouncers that would bother all modern day batsman with the exception of Ponting. However if the bowler is low 80's he's better off using the bouncer as a (very) surprise weapon, otherwise it is a waste.
