Danny, you do realize that everything you wrote did not exist in mankinds past right?
You just don’t seem to get how the immune system works nor how viruses work.
Please go pick up a freaking textbook on the human immune system and how virus move through humanity.
Here is a hint. One of the beauties of the human immune system is its use of a threat as a means to defeating that threat. You and your ilk only stand in the way of the beauty which is the immune system.
Many viruses have been eradicated from North America, because we refused to let them run their course. We went to war with them. Developed vaccines, tracked them down and quarantined them out of existence, eliminated their carriers.
The immune system might be a beautiful thing, but there is unacceptable collateral damage. Not getting viruses in the first place is even more beautiful.
Save your breath. This poster is convinced and will continue doubling down, offering suspect verification until they fall over on their keyboard from hypoxia.
