That's moving the goalposts. We were discussing the government act of implementing travel restrictions, as a policy. Rather than debate whether that is sound policy, you've retorted with "well he also said racist stuff...which is racist". This is why we can't make progress. Rather than address individual implementations on their own merits, all too often people are now lumping everything originating from the same decision-maker together and discarding the whole package.
>>>And what is the point of stopping flights from China only? When there were global outbreaks?
Because at the time (31 Jan 2020), ALL 210+ fatalities had travelled to China: https://www.washingtonpost.com/us-policy/2020/01/31/trump-we...
There was no spontaneous, independent outbreak of COVID appearing contemporaneously in Italy or the UK. A complete international travel ban probably WOULD have been the best idea (along with 90 days of Wuhan-style internal lockdowns). Short of that, a ban on the source nation of (again, at that time) 100% of the fatal cases seems like an appropriate compromise to not completely collapse confidence in the steady trajectory of the US & global economy.
>>>"Obama did it too" is not an argument.
It establishes precedent. Both for the policy itself, and that the deafening lack of "Racism!" criticism as proof of the hypocrisy inherent in the accusers today.
