I've been looking to start playing the Bird, and I don't really think the opening goes against the laws of chess so much as to be "refutable". 1.f4 targets the e5 square, and this control is increased with moves like Nf3 (and, in the fianchetto lines, Bb2). Also, should white succeed in his aim to get a second pawn into the centre on e4, he will control a lot of territory in black's side of the board in the centre and the kingside, which will facilitate an attack - let's not forget that the predominant objective of chess is to checkmate the opponent's king.
Since white starts with a one tempo advantage, 1.f4 seems like a fairly sensible way of opening, especially if 1.c4 is regarded as an attempt at getting an advantage from the opening. The weakening of the kingside, as with most f-pawn thrusts, is illusory with correct play, and possibly even of benefit since many people then try to destroy white from the opening.
Of course, as a KG/Latvian player, I'm probably a little biased regarding this. Yet, I feel the dutch is a bad opening... so much for logic eh?
Anyway, Taylor's new book does a much better job than I could of convincing someone to play this opening. One of the best books I've read in a long time - even if he does waste a little bit too much time on 1.f4 f5 2.e4 for my liking.
