This is a worthy video detailing the facts on the ground of migrants (and non-white minorities) within Western nations when it comes to crime and self defence. It is worth watching.
Here is my four line summary making the critical distinction that this is deliberate.
The state disarms its citizens and passes strict laws against use of force and especially any kind of force multipliers.
The state then imports millions of people from nations hostile to the West culturally, religiously and for whatever reasons.
The state then de facto, does not apply these new laws to the invited and state supported migrants, such that there is a noticeable and viceral imbalance when it comes to how state law enforcement agencies treat actual citizens of Western nations Vs. invaders. The most obvious De Jure example would be Sikhs being able to carry knives even in schools. But looking at sentencing of actual criminals who are caught with illegal weapons, we also see a de facto permissiveness towards illegal or invited hostile immigrants to Western nations.This results in enormous numbers of armed migrants hostile to the local population, doing attacks frequently enough that it becomes clear to all, consciously or semi-consciously that legacy citizens are second class citizens in their own lands and even homes.
The progression of events make it impossible to not know that this is deliberate state disenfranchisement of the legacy citizens of Western nations, except to the most determined leftists who will cling to their belief that this is a good thing and a form of justice, and the self blinding centrists who would rather feel good believing in a benevolent state than feel as uncomfortable as they should knowing how things actually are.
