The birth control pill is just much more convenient and does the same thing....prevents pregnancy.
???
Well, no. The Catholic Church supports other methods (for example natural rhythm method) which prevents conception and also results in fewer Catholics. It is the fact that some birth control pills prevent an already fertilized egg from being implanted that the Church objects to...the whole “life begins at conception” thing. Since the article is short on details, we are speculating as to Jindal’s intent here. The rest at this point is immaterial.
Your argument is self-contradictory, Sacajaweau. If some church were just interested in maximizing their numbers, they would ban NFP and celibacy (abstinence), both of which very effectivly prevent pregnancy.
However, they are not contraception per se. Contraception is engaging in a sexual act which has been deliberately altered in some way to sabotage its natural fertility. Pills, patches, implants, injected drugs, devices and surgeries that intentionally disable natural sexual function are contraceptive methods. NFP and abstinence don't disable anything or anybody.
