Calling people from other countries "savages from primitive cultures" is textbook hardcore racism.
Would you like people who think raping 12-year-olds is fine because their prophet did it, living in your neighborhood, and going from 10% to 90% of the local population?
Some cultures are just better than others. Some are downright evil.
People need to obey laws, not whatever morals you want to pick and choose for others to accept.
Also when someone says you are repeating white nationalist talking points verbatim, your response should be 'I didn't realize that', not 'sign me up'.
The West is (mostly) a "high-trust society". We obey laws and morals because we want to, because it's the right thing to do. Just think about it, how easy would it be to steal a lemon at self-checkout, or bump a car in a parking lot?! It's almost impossible to enforce the law on everybody.
Moving from a low-trust society to a high-trust society is almost impossible, and requires tremendous effort and extreme authoritarian measures (e.g. ubiquitous video surveillance (China) or military crime crack-down with mass imprisonment (El Salvador)). Our best bet is to avoid losing a high-trust society in the first place.
On top of that, obviously "law" and "enforcement" is just downstream of "culture". See e.g. San Francisco (where law isn't enforced) or statistics on black vs white jurists (blacks vote in line with race, not "for justice"). Or Muslim rapes in the UK (the victims went to the police.. who also raped them!)
So, yeah, I don't want people who believe that stealing, fraud or rape is normal, living near me.
Everything you put here could be a cut and paste from comments on white nationalist and neo nazi forums.
