First, as far as the issues, lets let Paul speak for himself..

Notice, that Paul wants to pass the Sanctity of life act (or even better, an amendment). That means that an unborn baby would be treated no different than any other person. If someone took their life...they would be prosecuted.
What Paul is against, rightly I believe, is any law that gives one group of people more rights than another. He is also against the Federal government intruding on the states rights to prosecute crimes as they see fit (as I explained in a previous post).
However, what these articles are referring to, is Paul's "We The People" act, which is a bill that Paul introduced, that would strip Federal Jurisdiction away from the Federal Courts, for not only abortion, but also prayer in schools, the teaching of Creationism in schools, and teaching of the Bible in schools.
What would this do? It would instantly make abortion illegal in 18 states, and restricted in 22 more. These states have so called "trigger" laws, which would go into effect immediately were Roe Vs. Wade overturned in such a way. It would also allow the state of Texas, for example, to teach the Bible in schools, and choose to not teach evolution, or teach the two views of Creation and Evolution both, and to pray in schools, etc.
All of this would happen instantly, with a simple majority in congress and the signature of the presidents pen. California, and New York, who presently hold a disproportionate hold over Washington, would be silenced in terms of Texas morality. And that is a good thing! It would also save millions of children's lives.
However, what most people do NOT understand, is that this would NOT prevent the Supreme court (or other federal courts) from hearing murder cases. Thus if the child in the womb were federally considered a normal person, these would not be effected by the law, if and when that got passed.
Now, on the gay marriage issue. Paul believes not only should the Federal Government get out of the marriage business, but the states as well! Although he recognizes the states rights to conduct there own business on such matters, he believes marriage is a church issue, like baptism, and the government should never have overstepped its bounds in the first place. The idea of the government issuing "marriage certificates" should be as offensive to the Constitution loving American, as them issuing BAPTISMAL certificates. The government does not have the right to define marriage. God has already defined it.
Understand this; once you recognize that the Federal government has the RIGHT to define marriage, in a country that is, again, largely controlled by New York and California morality, it WILL be used against the states to enforce "Gay Marriage" upon them. Instead of passing laws, lets do what should have been done in the first place; return marriage to where it was before the Government decided they needed to keep whites and blacks from getting married...return marriage to the church. Then, if anyone wants to "say" they are married, they can, but I can also tell them there not, without fear of legal problems.
I hope that clears up both my, and Dr. Paul's positions..
