6 years is not going to have a significant technological advantage. They aren't going to know what is happening if people suddenly get cold in collapse, they don't know if it is something inivisible, or some spell, or what. And we again don't even know if dementors can be killed by normal things.

You overestimate the morality of the common person. When the average people find out they are at war with a magical foe, there is going to be hysteria. Religious anti-demon fundamantalism will rise, anyone related to magic will probably have to be put under Muggle government protection (by reasonable western governments) or else be killed by vigilante groups. This would include any wiccans or other people who can be connected to magic, there is going to be mass hysteria. The goblins and centaurs most likely will know their condition will get no better by working with people who outright fear them and know nothing about them, and may even get worse. Even if there is a "magic gene", it isn't going to be able to calm the chaos and fear.

A 15 year old wizard is powerful enough to cause great concern to any random soldier that goes against them.
