I acknowledge your points are well-founded. Perhaps I’m being optimistic, but I just don’t see Americans — unlike modern socialist Europeans — standing by while their assets and livelihoods are taken away and, ultimately, their family’s personal safety is threatened by savages.
Americans will probably fight for the personal safety of their families, but they conceded the issue on assets and livelihoods when they determined white Americans could be passed over for education and employment in favor of much less qualified preferred minorities (including white women). The resulting emasculation played a huge role in driving us to a negative birthrate - voluntary extinction.
They already ARE being taken away - parents being stripped of visitation rights by the courts, assets are already being seized via eminent domain and forfeiture in the courts (losing their jobs due to hate-crime verdicts), and the means to defend themselves slowly being stripped away through incrementalism.
And the people doing it are the ones the herbiovores keep voting in year after year.
