if you think all the problems of society come from one specific group of parasitic organisms yet you don't recognise that parasitism is through and through the universe and the only real defense is called "immunity"

you are a very sad person

going at them with the bug spray is far less effective than understanding their DNA and crafting a set of techniques and policies to starve and exclude the parasites from the to and fro

sometimes even you get far more results by building systems that simply don't benefit parasites, a great example of that is Bitcoin, Bittorrent, truly genius inventions of antiparasitic technology
