Seems like a sensible theme to explore but is this data or conjecture? I'd make a similarly anecdotal conjecture that you'd be met with rigorous debate but your social character standing won't be affected by bringing this topic up, nor would it be socially acceptable for your opponent to use ad hominem at any point. This is the theme the author is addressing.
Even Justin Bieber is banned because 'he has engaged in a series of bad behaviours, both in his social life and during a previous performance in China, which caused discontent among the public', and he isn't even politically active or anything. China's public sphere is highly controlled.
