The borders by Colonialists in Africa maybe, but culture is very real though malleable. Would you be happy with the partial system of Chinese non-freedom of religion and imprisonment without trial ? How about forced conversion to Islam ? Just accept that not the whole world share the freedoms and mindset via hardship and struggles that your ancestors fought for. Just the language issue alone, do you really find it a given that the rest of the world would be happy to sacrifice their own for English. Look at what is happening in Europe, forced quotas of refugee uptake and immigrant accommodation, not only can you see the videos for yourself where welcoming Germans have to see how benevolent food parcels are thrown away at the very moment the immigrants arrive by train but tremendous friction in formerly homogenous , safe and prosperous communities with rape and murder commonplace by ungrateful overtakers. How about the Muslims in Britain openly threatening with Sharia Law to replace centuries of civilization, grooming gangs and the like. Controlled immigration where immigrants accept the status quo of the host country is one thing, but doing away with borders is so utterly ridiculous.Those are artificial social constructs over the years.
