I did.
Including Paul Lewis' response and the counterclaims by anonymous individuals. It is actually not a particularly strong case. The time period when it was released was during the control of a Military Junta that refused to yield power in what is arguably one of the poorest and most corrupt nations on the earth. A bag of rice will buy a child soldier, so how much can a 'witness' cost.
Setting aside both Lewis and the anonymous accounts, the facts on the former Burma are they had, have and will probably continue to have one of the lowest reproduction rates of any developing nation. This is not attributed to the terrorism of Baptist Missionaries, but the 1)late marriage age due to extreme poverty, 2) high number of voluntary abortions and 3) Budhist majority culture creating an acceptance of celibacy as a path to spiritual purity. These facts, unrelated to any human account, make the Lewis account that the sterilization was desirable far more likely that the counterclaim that in a nation of women who don't want babies, the Baptists found 20,000 who did to trick into sterilization.
You might want to dig a little deeper and show some healthy skepticism towards those opposed to Christianity as well as those supporting it. Burma does not pass the smell test.
Fortunately the Cultural Revolution came to Russia and China to eradicate the evil influence of Christianity.
How many people did those non-Christian efforts kill?
(You might want to look it up.).
[Hint: 30 million deaths by Mao; 7 million by Stalin]
God bless atheists for rescuing us from missionaries!
