To spell it out for you. If you can not disprove a rule interpretation, or show that it egregiously (to use your own word) goes against what could be accepted, that means it is RAW, and rules legal. Anything past that is RAI, RAR, RAF or a ruling. These are not considered the standard for rules legal. If you wanted an AL legal build, tough luck. You're stuck with rules as written, in all of its faulty glory.
Past that, if you're incapable of parsing any information that isn't spoonfed to you, I wish you luck in life.
Edit: You are entirely right, and I really should have come to that conclusion a while ago (I actually did, shortly before my "bait" post, but unwisely decided to continue, not wanting to give him an excuse). Unless he contributes something of serious value, I'm done responding.
