I'm sorry bro but you are an idiot and I will prove it. USA is built on white supremacy and blacks are oppressed, UK Ireland fought for independence and Scotland is increasingly doing the same, India has Pakistan and Muslim issues as well as rising Hindu supremacy against minorities like beef police, Brazil blacks marginalized like USA, South Africa Apartheid and land reform issues and Russia Chechen secessionists. Africa splitting up will bring peace by stopping tribalism. All the European countries are tribal and successful because the tribes are separate, England land of the English, Finland land of the Finns etc. Somalia was never united before colonialism and Somaliland wants independence from the wretched carcass of Somalia, Somalia isn't as homogenous as you would like to believe sharing different cultures.
And you're banned from this thread.
We already refuted your argument about only homogenous countries being stable. White supremacy or NOT the USA is the most diverse country in the world while being stable. You're just saving face right not. And your points on Somalia is weak as hell considering Somalia has always been united in history(look up Ajuraan empire), but more important you're changing the goal post as Somalia is STILL homogeneous via ethnicity whether it be Somaliland or not! And the UK is still one country. All countries start out as ethnic tribal wars end then become unified under a nationality. We've seen this constantly in Europe, Asia and slowly Africa.
