It seems that many people are intent at proving your original point, which is sad, but not entirely unexpected I guess.

Regardless, I agree 100% with this comment of yours. I can't extend the rational to not supporting contraceptives, however. To me it doesn't connect.

Allowing a young couple to increase their earnings/career potential by delaying childbirth directly relates to making the smart investment over the long term, as you relate. I should know, as I've done this myself. My children are much better off now and in the long term with a solid roof over their heads and two loving parents in a committed marriage than they ever would have been with a 20 year old father who was in the army and dating a woman that really wasn't good for him at all.

Your intentions don't seem to connect with the methods you are suggesting; I don't see any issue with your intentions however.
