Usually when someone legally says UCC, they think Uniformed Commercial Code.
The UCC is a body of law that has been accepted, more or less completely, by all the states to regulate commerce within and among them. This notion of shared commercial rules is very effective and felixible (as compared to general contracts and property law) so that parties can maintain business.
That said there is no UCC 1-207.

It should also be noted that the UCC only applies to commercial contracts, not property, services or a variety of other contractual relationships that parties may join.
That said, a very quick review of what this fellow says, indicates that he doesn't know what he's talking about.
As for contracts, it is generally a rule that you can't be held to contracts that you don't agree with. You can, for example, scratch out provisions of contracts and initial them, and then sign the contract noting that you did not consent to those provisions. I remember one of my old law professors telling a story about bringing his son to the hospital when he got hurt and then taking the time to read through and scratch out provisions he didn't like.
If you don't consent to a contract, you usually can't be held to it. There are exceptions of course. But a core rule of contracts is that there has to be a "meeting of the minds"- that both individuals have reason to believe that the other knows there is an agreement being made and an exchange of consideration.
Of course if you try to scratch out provisions in a contract and then get the other person to accept it. Good luck.
