I watched the whole video.  Russo's not saying the big problem is the income tax.  The big problem is the Federal Reserve. The thing is, all our income tax goes to pay interest on the debt to Federal Reseve, when we don't really need to be doing that.  Russo just goes on for a while about how income taxes are unconstitutional and there's no law that says you have to pay them.  Since there's no law, income taxes are being enforced by intimidation and big guns.  The IRS is illegally seizing people's property, etc., etc.--and that's the kind of thing that happens in a police state.
After that, he talks about all the other shit that's going on or is in the works that will be used to take away our freedoms. If I didn't pay attention to stuff like this, I would probably think the guy was on acid.  National ID cards, computer chips they want to implant in our arms, elections rigged by electronic voting machines.  I've done a lot of research and written reports about these things.  It's all very real, and it's all very scary.  
To the guy who was hating on Ron Paul's "family values," I hear you. "Family values" is just a phrase politicians throw around to appeal to a large group of people.  Unfortunately, for a lot of people in America, politics is limited to two issues: abortion and gun control.  Gun control is important because the harder it is for us to get guns, the easier it is to take away our rights.  If they make guns illegal, criminals will be the only ones who have them, and that would be bad.  Abortion, on the other hand...we've had a lot of Republicans in office and none of them have overturned Roe vs. Wade.  I consider myself pro choice, but I don't really care that much whether a politician is for or against making abortion illegal, because (1) it's probably not going to change, (2) I'm wouldn't have an abortion either way and (3) other issues are a lot more important.  I'm actually glad Ron Paul is "pro life" because some of the other Republican presidential candidates aren't, but most Republicans are, so maybe this way everyone will vote for him.
