Whatever happened to our right to protect ourselves and our property?

Check this story out - http://www.therant.us/usa.htm#0210.
When did it become a crime for us as US citizens to protect our families, property and homes from those who would destroy it?
This really gets my goat... our country is quickly turning into a socialist state, and this type of lawsuit is just the thing to start a drive to take property away from folks who have worked hard to get it, and give it away to anyone who wants it.
How long are we as citizens going to sit by and let our government destroy us? we need to remember that the main reason we were granted the right to bear arms, was to protect ourselves from our government.
