I should like to point out that right up until the 1930's Every Christian denomination was against contraception. Chastity was considered a major virtue. Now most "Christians" no longer distinguish themselves from the secular world regarding contraception, abortion, premarital sex and homosexuality.
Good point. Unfortunately with the rapes and prostitution going on in impoverished countries some sort of means to prevent unwanted pregnacies may be warranted. These poor women (girls?) have no where to turn for assistance in guidance on what to do with their lives. They have no jobs or husbands to support them. Yes in an ideal world chastity is great. But some people don't live in an ideal world but a desparate one. And to bring a child into some of those environments would be reckless.
