Jaberwok I abhor cruelty to animals too. The point I'm trying to make is that, unless one is a vegetarian or vegan, it's really hypocritical to criticise other countries about their eating habits. Animals for consumption in the UK aren't treated very well either. Wild animals are for sale and, in the case of lobsters, they're boiled alive.
Knowledge about China's treatment of animals isn't new, nor is their general human rights record. A million Muslims in the western part of the country are being treated abysmally (as are Muslims in India), but there hasn't been an international outcry. Educated Chinese know how their government treats them, but it's not that easy to leave the country or do anything about it.
This is the third thread on GN about Wuhan market and it really does seem that the issue of animal welfare is being politicised. Yes, China has questions to answer about its handling and initial response to the Covid-19 outbreak. Yes, it needs to enforce existing laws about illegal markets, although ironically it would face criticism for being even more authoritarian than it is. Interestingly, I found an American website complaining about the government banning the sale of bush meat in the US as an infringement of civil rights.
However, this does seem like an excuse to justify some kind of cultural war against "others". It's what usually happens in a crisis. People seek to blame others for something they can't control.
