In this case, stop capping/rabbiting and reinforce your team's defense. You apparently know how a good CTF strategy looks like, so be a role model and defend.
I do defend. Problem is, my idea of defense is to do everything to keep enemy team from capturing. I'm a chaser and grabber. If I can't catch the fc, I go for the enemy flag by a more direct route and nab it before fc can get there to cap. What always ends up happening is my entire team is all caught up in engaging the enemy defenders in their base instead of 1) returning our flag, 2) making sure our flag base isn't being sat on, 3) being ready to defend in case the flag is returned. Taking the flag and capping it is, to me, secondary. I grab the flag as a defense. Of course, once I HAVE the flag, I am on offense and must now either cap it or pass it--and guess what

No one is ready for a pass! Yay!!!
You do realise that you're setting up an inconsistent role model?
Lemme spell this out: Your teammates think that they don't NEED defense since enemy can't kill you anyway while you're rabbiting. That's why they don't bother defending, instead they'll head straight to enemy flag carrier.
Other team is complaining simply because you're being un-sportsmanlike: It's almost like playing Doom (1 or 2) Deathmatch with your friends with one guy having IDDQD active. Try and shoot down a rabbit (all by yourself) traveling at 160 kmph and you'll see why the other team is complaining. If you're really against rabbiting, for God's sake DON'T RABBIT!
I have to rabbit because no one is defending, not to make a defense unnecessary. How the hell am I supposed to cap the flag or pass the flag if there's no flag and no friend to do so? The moral of the story is that there is no end to a rabbit match until the team starts a defense. I often lose count in the first five minutes how many times I punch in "CDC," BEGGING my team to give us more defenders. After a few minutes of that, I start telling everyone that I'm gonna start rabbiting if they don't shape up some D. Since most people loathe rabbits regardless of whose team they're on, I would think that would get a reaction. But no. It never does. The only reaction I ever get is, "RABBIT" from the other team.
On a good day, where my team is defending, I prefer to sit in the base so that I can cap as soon as the flag is returned. I can't do that if I'm alone in OR gear with four chasers on me >_< .
Doom is a little bit older than me, I'm afraid... My brothers were playing that while I was still *baking brownies* in diapers (I'm 20, now). Point is I'm not getting your analogy, but I think I understand what you mean anyway. And believe me, I HAVE tried chasing a rabbit alone at 160 kph. It sucks every time, except the rare instance of a lucky burst of CG that kills him in mid-air.
