Voldemort had the right idea

The existence of families such as the Dursleys proves that many are already aware of magic in the world. When the war begins, the inspector who Harry asked the location of Platform 9 and 3/4 who had no memory spell cast on him (since Harry cast no spells in the first film) would just go and tell the authorities. Even if you wipe phones, people still remember, and if not, the governement can just check for cases of reported amnesia. And finally on the tactical side of this, so? Just because you can remain hidden doesn't win you the war. When exactly will the human race die out here? You'll only be able to wipe out humanity with full scale war, and no amount of memory wipes or cloaks can hide you from that. Humans reproduce too quickly to wipe out like that, and if you make them engage in war, then there will still be survivors, and civilians, because only nuclear war could wipe out humanity now, and that would destroy the entire world. Not even wizards can wipe out humanity now. Now, on your evolution argument, (if we're mixing science with magic here, then anyone using an invisibility cloak cannot see, as light does not enter the cloak and they are rendered blind) natural selection works with evolution. Whichever species reproduces and survives more effectively wins. Humans wiped out Neanderthals not with stealth, but with fire and spears, in fact, we don't even know if they fought at all, perhaps they integrated and made their own "squibs". But it was survival; the ability to live in both warm and cold climates, to create fire, this was the winning difference. Since wizards are still too few in numbers, they cannot win this evolutionary war, and why do you see evolution as right anyway? If we are on the premise that I am a muggle arguing with you, a wizard, then doesn't that just mean the new evolution will just wipe out you as well? This cycle of eternal violence seems flawed to me. Squibs are evidence that humans and wizards can live together in peace. And as a final point of rebuttal about the hunting for sport thin, neanderthals never hunted for sport, only for survival, as they survived by the skin of their teeth. Conclusion; This war would go on for hundreds of years because of the slow method of guerilla tactics, and humans reproduce faster than you can kill them. Eventually, humans will either have technology to counter magic, or harness it themselves. There is no real premise for wizards being superior other than magic use, because other than that, they just seem like really pig headed humans (e; Voldemort, all death eaters, Malfoy family, Snape (pre deathly hallows plot twist), the entire council who let Dolores Umbridge take over Hogwarts, Dolores Umbridge herself, the health and safety department for Hogwarts, the list goes on...) and life would be just as violent with them in charge, except without electricity, education, social security, (just see life of brian for the rest of the list of things wizards don't have) In fact, with wizards in charge, the number of wild monsters such as trolls and (I am not going to pull up a list of dangerous creatures, you know them) this will only lead to more death and danger. Communication which relies on animals will cut off ties with other countries and the world will be a much worse off place. This is why Voldemort would only have made things worse by trying to wipe out humanity (and also why the wizards should have just asked the muggles for help killing Voldemort, or just should have blown up Slytherin tower, killing all the villians of the series at once.) See you next time, Duncan.
