The West now mostly embraces the culture of death which permits women's bodies to be invaded by the life destroying practice of abortion. If we permit the mutilation of unborn children, a practice which results in the destruction of the unborn child and frequently results in the physical and psychological mutilation of the mother, why all the kerfuffle when woman are subjected to FGM?
In the good/bad old days of the Empire, tribal customs such as the immolation of widows (Sati) was common until the 19th Century when the Brits "imposed" their western ideals upon local populations which then began to curb the practice. No one is saying the British Empire was perfect. It did, however, bring education, ordered government, health, public works (sanitation, etc.) and the rule of law to lands previously ruled by ruthless warlords who routinely eliminated people on a whim. Sadly, many of the those countries have returned to their pre-colonial madness.
