Combatting Telekinetic races

[Mylon]

How do I take on telekenetic races effectively? So far I've had limited success with telling all of my planets to build fighters and guard warp points, but I can't get anywhere near matching them in ship to ship combat. The first difficulty is the obvious allegience subverter. This weapon in itself quickly spell doom for a crewed ship regardless of anything (and self destruct devices don't help in this case!) and master computers add nearly two turns onto production time for my ships, in addition to the relatively large maintenance cost. And then there's those telekinetic projectors that do a pretty large sum of damage... So how do I effectively combat them with practically 3/4ths the ship power thanks to computers? Unfortunately I can't get enough armor on a single ship to try boarding tactics because they can easily do 840 damage per turn (4 telekinetic projectors or so). Any suggestions?
