Looking at the additional points bit at the bottom (because I don't know where the original column was & hence can't read it), I'm not sure what the fuss is about. He's definately right that troops don't need blind support (blind support is essentially worthless), and that it's better to have material support than to assuage guilt at sending people to die by pinning ribbons to trees, etc.
Perhaps there's something more deeply offensive in the column than is quoted or mentioned here, but from what I can tell is that he thinks blindly and blandly supporting troops doesn't mean anything except a back-handed endorsement to the war as a whole, and if people do want to support the troops and not the war, then they should be agitating for better equipment and shorter tours; on reading, it seems he's not defining that support as - materially - being not wanting them to get hurt (hence why the stuff about body armour, shorter tours is mentioned).
Certainly the guy who's quoted as comparing him to Bin Ladin appears to be an off-his-nut reactionary.
