the great mask debate

Mhh I've been hearing this, but I'm not sure if I believe it

Never before have I heard of asymptomatic spreaders

It used to be, if you were asymptomatic you also were NOT contagious

I just can't help wonder if this actually changed, or if it just fit the narrative
Asymtomatic carriers of hepatitis have been around for a long time. No symptoms but spreaders.
