Can't say I agree with booing the team off either, purely because it would give the opposing team such a buzz to hear us booing our own players, although I do agree that by cheering them all the time even when they play bad and can't be bothered seems pointless, just don't think booing is the answer.
I do agree with Henry bringing the team down. I no he has played with injury but he is the captain and when his head goes down (which it has a lot when things haven't gone his way) it brings the rest of the team down as well. I've heard a lot of people talk about loyalty and everything he has done for the club and don't doubt that on his day he is world class but I also remember him waiting till the very last game to tell his adoring fans wether or not he wanted to play for Arsenal anymore.
Nether the less as long as he wears and Arsenal shirt I will still continue to sing his name from the terraces and gun down any non Arsenal supporter who tells me he is anything but brilliant
