Don't be stupid. There were countless elections and opportunities to stop it, with whites as the majority of the electorate. Nobody did a thing. They kept voting for the same parties, the same corrupt politicians. This applies to the UK, America, and most other western nations as well. Democracy is the embodiment of personal responsibility, and our governments capitalize on the fact that nobody gives a shit what they do so long as their short lives keep on running smoothly.
Unforgivable tragedies took place, terrorism, rape gangs, and still - nobody lifted a finger.

The majority happily surrendered themselves to comfort and this is the result. Jews are worthless parasites, but they only gained power because the European majority gave it to them, in contrast to the past when they were readily driven out. Rome fell because of the choices of the Romans, and this is the same. The only way out now is cataclysm, but since that is not forthcoming we can expect demographic changes to accelerate until it arrives.
