At present, there is zero proof that asymptomatic transmission actually happens. All the "evidence" cited in favor of this flimsy hypothesis is pure speculation. The WHO said it occurs "very rarely". That caused a backlash among the liberal mob, so the WHO "clarified" that they "don't know the answer". In other words, there is no actual proof that it happens. Liberals desperately want to sustain this narrative because without it the justification for disastrous lock downs and masks falls apart. Liberals NEED the news to be bad and scary all the time. They absolutely refuse to acknowledge any good news at all. They want this crisis to drag out for the remainder of the election cycle at the very least. This is all about defeating Trump in 2020. It has nothing to do with public health or safety or science. Those are just pretexts meant to conceal their true motives. And it's obvious.
