@i_petersen @SuzieSm28138769 You're still arguing against the strawman of masks being a 'silver bullet'.
Masks aren't the only available measure (in fact not even the only measure present now) and the combined effect of multiple measures with individual small effect is not necessarily small.
@i_petersen @SuzieSm28138769 你还在争论口罩的稻草人是“银弹”。
口罩不是唯一可用的措施（实际上甚至不是现在唯一的措施），多个措施与个别小影响的综合影响不一定很小。
