also as the economic situation in european countries worsens and the ethnic conflicts increase the replacement will slow down.(and hopefully eventually reverse) the quiet replacement is only possible under good economic conditions with enough money for gibs. most non european migrants here are here for gibs so if those dry up these parasites will either go home or chimp out, in either case the status quo won't continue. you can't maintain european societies with 50% brown parasites, it's simple as that, collapse would happen long before that point. obviously it's different for the usa/aus/nz since unlike the average muslim migrant in europe their migrants are of a bit higher quality and their welfare system also isn't as generous.
