Protip: Work on using more details. Speaking in generalities makes you come off as slightly insane.
On the contrary, I find anyone who would defend Ron Paul as anything other conservative christian theocrat who believes in pillage and burn economics and is willing to abuse or tear down the federal government to get it is slightly insane.
On DOMA: section 3 specifies that same sex marriage and civil unions are not recognized for any federal purpose, including military spousal benefits and social security survivors benefits and tax returns. Its not just about protecting anti-gay marriage states from being forced to recognize gay marriage and civil unions, it prohibits the us federal government from recognizing gay marriages and civil unions.
It explicitly uses the authority of the federal government, a violation of his anti-federalist position (but its ok because its used against the scary gays) to strip rights and entitlements from people, even when those rights and entitlements are being recognized and protected by states. It protects the "States rights" of states that are banning gay marriage and civil unions, but violating "states rights" for states allowing gay marriage and civil unions.
the WTPA explicitly enables states to enact laws that infringe on privacy, religious and gender issues without challenge or rebuke by the supreme court. If it was passed, it would mean that Utah could pass a law that only Mormons could hold office, or Michigan could make practicing Islam a crime punishable by death. The supreme court of the US is the last line of defense against the passage of unjust law. And the WTPA is designed to break that last line of defense against religious and gender/orientation oppression at the state level. It is basically Ron Paul trying to worm his way around the 14th amendment and the incorporation doctrine, but only for the specific ways that he wants states to be able to oppress people rights. This law really is that bad.
