Western governments will never give up that global apartheid system, unless they have no other choice. They will need be forced into accepting terms. This means their militaries and other institutions need to be thrown out of the colonies, and they won't go without a fight. It means they need to lose all leverage over international trade and finance. When they are defeated and no longer able to exploit, the border guards will become pointless and self-defeating. I think and hope this would also trigger/coincide with a revolution in the West, but who knows. The Western countries will have to change for sure.
Then you go on about rights and freedoms, but this system does not meet the basic needs of most humans, does not respect their human rights, and the majority of people are therefore far from free. Do you think your freedom hinges upon oppressing others? Because that's absurd. Are you thinking of privilege maybe? I guess privilege is a kind of freedom, just not for everybody.
You can be an atheist in very many poor countries with no problem, and LGBTQ rights weren't very good in the West not so long ago either, and seem to be getting worse. I expect reactionary attitudes to go down globally when this injustice is addressed. In the third world, reactionary attitudes are pushed by the comprador ruling classes there, often by allying with religious institutions, and driven by a desire to fight socialists. In the West, the recent fascist wave is caused by a desire of the ruling class to maintain power and profits, firstly by blaming scapegoats and secondly because the fascists are more willing to use violence to crush the opposition and uphold capitalism and imperialism. Hence why they're getting money from billionaires. All this reactionary shit is intrinsically linked to the need to maintain the exploitative status quo. Heck, this whole argument started about borders and the fascists are the ones that advocate for the most brutal border policies. Why? Because that strengthens the system. The system is in crisis, and fascists are needed to keep it going with violence, as it might collapse otherwise.
