For one, I was never "talking down to you." I was presenting an argument for your position, and, now that you decide to start bad-mouthing, I'll counter.
You've never played the Freespace 2 campaign. I can assume that through the fact that you apparently don't recollect the mission "The Sicilian Defense", where, in an assault on an NTF Orion-class destroyer, a Sobek-class corvette jumps in on its broadside to assist you. Now, without destroying at least one of the Orion's beam cannons, the Sobek is almost guaranteed to be destroyed in one salvo from the Orion's main turrets.
Apparently you've not well-considered your "stupid bunker" theory. If you're referring to a planetary-based launch site, the power requirements to escape the atmosphere and gravitational pull of a planet or moon would make the time to charge the subspace drive ineffecient; hence, the fighters (and especially bombers) would not have the same quick response time that they would if they had simply been launched from the hangar bay of a destroyer, most of which destroyers deploy their fighters directly into the heat of a battle, or quickly enough into clear space and with little energy cost of the fighter's engine to allow a quick jump into subspace to respond to a threat.
And Orions, in case you haven't noticed, have a very high probability of engaging and surviving against medium-sized Shivan warships. Remember those two BGreens that it can bring to bear? Those could very easily cripple or destroy Cain-class or Moloch-class warships easily. As for Lliths and Destroyers, the Orion has a fighterbay for that: deploy bombers and strike fighters, take out the Shivan beam cannons, then torch the Shivans.
As for the carrier sequence, it seems that, once again, you undermine plot and strategy. While a carrier would indeed be effective at simply retrieving/deploying ships in one area, you miss one primary consequence: vulnerability. Even if you did add large amounts of anti-fighter/bomber weapons onto its hull, you miss the problem with those "medium-sized Shivan warships", or anything corvette-class and above. The carrier, with the exception of its docked fighters, which may very well be away on a sortie, as you describe, has little defense against these large capital ships.
Hecate-class destroyers are intended to serve as flagships, not as front-line assault weapons. Orions were birthed in the need to deliver heavy firepower during the Terran-Vasudan War right at the frontlines of major battles. A Hecate only engages when it must, or if no other heavy support is present for the player. The Hecate was created in a time of relative peace, with no real need for a frontal assault weapon.
With your arguments, it seems to me that you are indeed a child, and have little room for your own "strategic thought". There. Accuse me of "down-talking"?
