The Federal Assault Weapons Ban only expired in 2004. There are also similar bans in individual states, whereas C+ gun legislation would essentially be taking the "right to bear arms" to an extreme. Even if only some weapons are only banned in some states, that's still different from "anyone can own any type of gun at any time".
See also: Brady Handgun Violence Prevention Act (background checks):
From 1994 through 2008, 1.8 million attempted firearm purchases were blocked by the Brady background check system.
And the Gun Control Act of 1968:

http://en.wikipedia.org/wiki/Omnibus_Crime_Control_and_Safe_Streets_Act_of_1968Regardless of whether or not you think legislation is too lax, or not enforced well enough, the fact is that there is still a lot of extant legislation on who can get guns and how, and that it IS enforced, although the degree to which it is enforced is obviously in question.
And regarding partial birth abortion:
On October 2, 2003, with a vote of 281-142, the House again approved a measure banning the procedure, called the Partial-Birth Abortion Ban Act. Through this legislation, a doctor could face up to two years in prison and face civil lawsuits for performing such an abortion. A woman who undergoes the procedure cannot be prosecuted under the measure. The measure contains an exemption to allow the procedure if the woman's life is threatened. On October 21, 2003, the United States Senate passed the same bill by a vote of 64-34, with a number of Democrats joining in support. The bill was signed by President George W. Bush on November 5, 2003, but a federal judge blocked its enforcement in several states just a few hours after it became public law. The Supreme Court upheld the nationwide ban on the procedure in the case Gonzales v. Carhart on April 18, 2007. The 5-4 ruling said the Partial Birth Abortion Ban Act does not conflict with previous Court decisions regarding abortion.
The current judicial interpretation of the U.S. Constitution regarding abortion in the United States, following the Supreme Court of the United States's 1973 landmark decision in Roe v. Wade, and subsequent companion decisions, is that abortion is legal but may be restricted by the states to varying degrees. States have passed laws to restrict late term abortions, require parental notification for minors, and mandate the disclosure of abortion risk information to patients prior to the procedure.
Also, federal funding for abortion is sort of up in the air, I believe. All these things tell me that yes, abortion, at least in certain forms, is definitely discouraged - and in some cases made a crime - by the law.
At this point I feel like you're just arguing for the sake of arguing, honestly.
