Doesn't actually matter if he is being nit-picky over the words Biggsy, he's still wrong anyways.
He's trying to argue semantics and he's arguing himself into a corner. It'd help him to understand the words he's using in the first place rather than throw them in willy-nilly in order to try to appear intelligent.
There is more than one definition for the word 'support', it has many in fact, this is by no means an exhaustive list, just the first one I stumbled across.
(yes I realise I'm a pedant!!
)
