The appointment of Carrie Lam was a mistake and I have no idea why the CCP did it. If the original claim is that CCP/Xi was irrational for appointing somebody who had a past record in somehow inciting mass protests (she was responsible for the reform bills in 2014 that sparked protests on similar scale), then yea sure I'll take that.

What I was responding to was the claim that "Xi ham-fistedly forced through a badly-written security law". This really isn't the case, and if your argument is that "well, everything done by the government is attributed to Xi personally, I rest my case.", I guess you're right then. Whatever you please.
