The countries in the past didn't openly declare their intentions of genocide in the years and months leading up to it. The person is ignorant of history. It is possible that some countries which committed genocide didn't even intend it or premeditate it and it just happened as the persecution gained momentum. The author does not account for that possibility either.

If some countries aren't letting people shop in shopping centers and other countries are letting unvaccinated people die in hospitals and are building Covid quarantine camps it's obvious that they don't really care too much about the lives of unvaccinated.
Can you promise that they will stop tomorrow and that it's not going to escalate?
Again, the steps have been fulfilled so far and it isn't even denied. Your rebuttal is that someone random you plucked from a website on the internet doesn't think so, as if genocides are always premeditated as a "plot" or are openly expressed.
