Beware of the new crop of rookie troopers on the road. I have had some decent encounters with troopers and some bad ones. By running your mouth you are setting yourself up for a bad time. There is no benefit to telling them you are legally armed for either party involved. If they ask, tell them, but never offer the info up freely. Did you also tell him that you were going to use free speech and not let any government troops be quartered in your home?
Cops should only worry about "illegal" guns. Your gun poses no threat to him / her and you should not justify the anti-gun terror by telling them you are armed. It is your right and none of anyone's business until you are asked to step out of the vehicle. I understand you did it out of some misguided feelings of respect, but you are going to find out the hard way that the respect you tried to show is rarely returned by the cops in our corner of the country.
THIS. You might want to read IGWT's post a few times for it to sink in.
