Asher I think you're overreacting a tad here.
You were happy to make a call on the dandy physicist's sexual orientation (I think that's fine btw) and a few other things besides.
James is offering up some lovely portraits, most of which appear almost as caricatures which leads us to ask the questions about their lives and interests.
I reckon Tom's observations are probably mostly accurate.
I was happy to make broad assumptions about the "clever cowboy".
Are we all overstepping the mark? I don't think so.
As to Tom's sarcastic streak, you need to remember that Aussies of a certain vintage have certain birthrights (well birth rituals really) After the quack (don't worry Asher it's an affectionate term) slaps us on the arse, they get the scalpel out, no, not necessarily for circumcision, that's optional, more for pressing matters such as surgical implantations.
First they whack in a big slice of sarcasm, this is not taken lightly and is always complemented with a big (bigger) slice of self deprecation. Next they find room for a big warning and alert system, it's called a wanker radar and it never fails, it works for your entire life, so much so that when working in tandem with the self deprecation tool, it's quite common for Aussie blokes to admonish themselves in the mirror most mornings
" look at you, ya big tosser!" for example.
This is an extremely valuable surgical implant, stops most of us from going insane.
We don't actually get a sense of humour implanted, this one you either have or not. If you do have one, we get a set of upgrades including irony, pathos, and ability for puns and double entendres.
Anyway, as I said, I think it's OK to look at James' image of the "Clever cowboy" and have one's wanker alarm go off like there's no tomorrow.
I do also know that Tom for all his (self aware) faults (pick your own expletives here), may be fattist, prattist and wankist - is not actually racist. Staunchly not so.
