Virtually all of the "migrants" coming into Europe are males.
However, unless they are interbreeding through rape, or the small percent of the migrants which are women are continually pregnant, or there is a massive increase in race mixing (all three of which are not happening) this is a 1-2 generation problem, demographically speaking.
(I anticipate that most people will misunderstand what I'm saying here, or will say I support it somehow or something, which is not true)
And they know that and still come, which means they don't come with natural plans like creating families, they come expecting their lives to be used for a different purpose, that's how you know they come for war
Oh many of them are believing that the white women are waiting just for them. And that leads to rape. And you only need some minor legislative changes to encoruage that rape culture. "That is a cultural thing. We should respect their culture! We have to be tolerant!" they will say
Fair point.
