A similar issue is that of female genital mutilation/cutting. Is it right that 7+ year old girls have their genitals carved up due to longstanding cultural practices, when they have no say in the matter? Many (myself included) would argue no. That's the tough balance, human rights versus the autonomy of these groups and nations.
You get real, despite what you watch on TV, Africa isn't just some Warlord rampant shithole filled with ebola and AIDS. There are certainly and definitely those in parts of Africa, but there are plenty of African nations in Southern, Western and Eastern Africa that have woken up and are trying to better themselves and the rights of their people.
I'm a libertarian transhumanist, I believe most of everyone should have the rights to be free of ethnic, religious, sexual orientational and political descrimination if we are the evolve as a species.
Of course there are countries that stand out and are progressing slowly but surely. But it still doesn't mean we should put our 2 cents in. Strong arming isn't going to do much other than cause dissent. Change should come from within. It is their culture, so it is their's to change.
We've already done the whole, "Big Brother West", tactic before and it's done more damage than good.
I think the point here is nobody is advocating for Nigerians to dress in kimonos while sitting down for a nice eloquently set up tea party to later spend the day shooting cans and making moonshine.
Just encouragement and non-militant aid to a government that has more freedom for it's citizens.
It took centuries of social turmoil, war and violence. It absolutely required force. Internal and external is irrelevant. Countries are just lines on a map backed up by historical accident and force of arms.
In any case if you were on the losing side of the cultural wars in Europe in the last 300 years or so you damn sure would've felt forced to change by outsiders to your socio-cultural circle.
No what I'm saying is that there are no easy answers and if you brush it off with trite lines like "no good comes from interfering" the price you pay is having to sit back and watch as injustices and atrocities occur while you do nothing.
Your choices are interventionism or non interventionism and both are plagued with moral hazards.
