Every so often a politician says something with which no one can argue. Today is Senator McCain's turn. In Annapolis, he said:
"If you find faults with our country, make it a better one. If you are disappointed with the mistakes of government, join its ranks and work to correct them,"
The problem, of course, is getting everyone to agree on the faults and mistakes, and how to better or correct them. Fortunately, democracy requires only that you get a majority to agree. You should try to convince everyone, but you don't have to. That means someone will probably disagree with your diagnosis, call it a mistake, and try to correct it. Your obligation to that dissident is to treat him as a fellow citizen and not an enemy. When you're the dissident, that obligation falls on the party in power. If McCain takes his own words seriously, and means his invitation sincerely, we should see the proof during the campaign to come.
