I don't think you're being rude, but you're wrong
English beer is around 3.5% to 4% alcohol by volume
Imported lagers (common in the UK) are 5% alcohol by volume
XXXX Gold is 3.5%
XXXX Gold is on par with the weakest English beer and the Poms drink on average the same number of pints as Australians drink schooners. So I doubt the beer was too strong for him.
Unless by overwhelming, you meant it tasted so god damn awful his stomach was in revolt?
That could definitely be the case.
What got me about this whole case are two points
One, he was held down and kicked - didn't throw a punch and gets charged with assault
Two, he was only charged when someone pointed out he was a Titans player.
The whole thing stinks and I hope the bouncer is the one who has to answer for his behaviour
