"Filthy foreigners bring in disease" is very big at Sinclair Davidson's Catallaxy

Basically, I don't understand why, in order to maintain their reputation, RMIT doesn't tell Sinclair Davidson that he can't run a blog for appalling, racist conservatives and still work at a university that hosts a lot of foreign students.    

Look at these examples:  he doesn't expand on it in the post itself, but it is clear from the post title that Catholic conservative-in-denial CL thinks Trump is on a winner with corona virus because he will be able to play it as a case of "filthy foreigners bring in disease":

Good luck: Disease-o-crats campaign on open bug borders 

(I won't link - you can google it if you want.)

But even worse is this comment in a thread (which is fully supported by other regulars) by another crusty Catholic, who even has an Asian wife (probably Filipino - so she's OK, she's Catholic.)

The World Health Organisation is utterly useless. It is run by palookas like that Rudd sheila for Pete’s sake! … who cannot even spell “honest”, let alone know what it means. The executive board is 34 nations – they include Sudan, Djibouti, Tanzania, Zambia, Burkina Faso (say what?), probably Haiti and a whole lot of other failed tribes of no consequence – directing how the civilised world should keep is people healthy. Fabulous – they are barely literate, you can forget them....

The demanding unpleasant little Irish p00ve from Qantas will have been throwing his weight around Canberra on Week One protecting his airline’s cash flow and his massive pay packet, followed by a conga line of tourist associations, the retail traders representative, heads of commerce flogging insurance and bank loans, the English language schools and universities who rely on their Asian students for their very survival, and so on. Not one of these people has any interest in public health protection – its someone else’s problem. They will lie handsomely to safeguard their corner.

Further, we have a government and a bureaucracy that is still shipping in illegal Centrelinkers from North Africa, the Middle East and other primitive places, people who routinely have a bog in the street and who don’t bother bathing. When they spit everywhere and shove their dirty mitts into the bowl from which the reffo next to them takes his next mouthful – and contract a gutful of Corona Virus 123 by hundreds – these public servants will ship ’em in by the truckload to the same hospital wards as Australians, because diversity is our strength.

 Sinclair even appears in the comments thread, with apparent intention to mock the catastrophising of the fatality of the disease, but not to tell anyone that they are racist pigs.

Not good enough for RMIT, I would have hoped.
