is that the disease is killing a lot of people because it's hugely infectious, not because it's particularly dangerous to those who get it. So supposedly a huge number of people have gotten it but only a tiny fraction of that big number have died.

This wouldn't mean it's not a problem. But it could conceivably mean that social distancing is pointless. If we're all gonna get it, and a few hundred thousand people are gonna die from it no matter what we do, then by shutting down the economy we're just delaying the inevitable. We should suck it up and let it burn itself out.

At least that's the closest thing to a rational argument. (The data on this is veerry sketchy at this point, which they never admit.) Unfortunately it also travels in the same conspiracy theory world as 'covid19 is a hoax!', or 'only fat and old people are at risk' (as if such people don't matter), or 'it's just the flu,' or 'vodka will disinfect your throat.' So even if it turns out there's something to it it really shouldn't be dignified with as much attention as it'll get.
