Dear Joan,
Please do not apologize. It was not your job to 'support the troops' and I for one thank you and many others for raising hell about the war, thereby forcing the draft and the war to end sooner and save many soldier's lives.   

There was and is no crime in being a real citizen and speaking up. If anyone needed to apologize it was MacNamara and his buddies.

If the flagwaving patriots failed to meet the planes and welcome the boys back appropriately, it was not due to your speaking and singing out according to your beliefs. Don't let them cow you into thinking you're to blame for their failure.

Sincerely grateful,
The rest of us
