It seems that you are being obtuse to prove some kind of point about how masks are useless and this is a grand conspiracy, especially since you have linked to a “QAnon” YouTube channel, but I will play along.

In this video, Dr. Fauci discusses the usefulness of an individual wearing a mask. The conversation is specifically about a mask’s efficacy in preventing the wearer from becoming exposed to viral particles.

Dr. Fauci expresses concern that individuals will believe they are more protected than they actually are, and they may be lulled into a false sense of security, as any mask except a properly fitted N95 respirator will not actually prevent you from inhaling sufficiently small droplets containing viral particles.

Dr. Fauci also expresses concern that the general public may not understand how to appropriately use masks by which he means that it is imperative that wearers do not touch the outward facing part of the mask and contaminate their hands and that they don and doff the mask appropriately.

Neither of those concerns have anything to do with the entirely separate societal benefit of individual mask wearing by preventing you,as a potential symptomatic/asymptomatic/pre-symptomatic carrier of COVID, from contributing to the infection of others. At a minimum, masks reduce the volume and the distance you spread viral-laden droplets by talking, coughing, breathing, etc.

It is also worth noting that your linked interview appears to have been recorded before the push for mask wearing as a potential guard against transmission was a part of public discourse. This explains why the second point is not mentioned.

As an aside, I hope that you can see your way out of this conspiratorial mindset. I am sure you are, like many on this forum, a very bright person, but you have to understand that by posting these things and contributing to the spread of misinformation, you are going to harm people.
