re: If you're outraged over the Michael Sam thing, turn the tv/internet off.

Thanks! But did you read the entire section of verses and not just the one small section? You can't take them out of context, and you must understand the background and history of what is going on. In Matthew, Jesus was talking to the Pharisees. They were criticizing Jesus and his disciples for not following Jewish tradition. The verse, or law that Jesus is referring to is back in the old testament. (See the Mark 7:10 verse you alluded to) The beginning of the quote in Mark clearly says that Moses said this.

Jesus was telling the Pharisees that they were preoccupied with keeping their traditions and not with keeping God's law. He was NOT advocating that we should kill children for disobeying their parents, rather that we should be more concerned with keeping God's commandments.

Now, Jesus was there to create a new covenant. We are no longer bound by the law, but are under grace. (However, the Parisees would not have understood this, because they did not accept Jesus as the Messiah, so Jesus had to use an example (Moses' law) that they would understand)

In both instances, this was referring to old testament law rather than new testament grace, or the new covenant. I know this is confusing, but I THINK I can find a link that might explain it more clearly if you would like.
