My world view does not accept collateral damage of individual in favor of religious beliefs, it accepts that properly adhering to the beliefs would almost entirely eradicate the collateral damage and is therefore the best course of action. As to your question of reasonableness, actually, yes, I do find it to be quite reasonable. There has always been sex outside of marriage, but the prevalence of it doesn’t mean that we should ignore morality to accommodate those who chose to ignore it. The widespread acceptance of sex outside of marriage has contributed to the drastic spread of STDs, and using condoms to avoid them is only trading one evil for another. If the only valid measurement was the decrease in STDs, you’d be correct, but that sort of view only looks at the ends, and not the means used to acquire them. Killing everyone in Africa would also reduce the spread of STDs, but that wouldn’t make it a good course of action. (I know that is a drastic comparison, but drastic does not mean invalid. The ends do not justify the means, and with the safer sex programs, one of the proposed means is blatantly immoral, and therefore no better than the thing is seeks to prevent. Given the fact that we view the salvation of the soul to be infinitely more important the salvation of the body, I’d argue that promoting the use of immoral methods is actually worse than the thing the method tries to prevent).
