I got the reply postcard today, excusing me from jury service. I asked to be excused under the question, Are you a US Citizen? I did not circle Yes or No, but wrote "see Remarks", and in the Remarks section I wrote: "Without a constitutional amendment, I do not have full and equal citizenship in the US."
Today I was excused, for this reason, since I gave no other. If anyone joins me, please photocopy the summons before you send it in, and then the reply when you get it. If you are not excused like I was, then you have the choice of going, but explaining that you cannot serve. If forced to serve, then you have the choice of abstaining from voting.
I also thought that if forced to vote, I would vote for the minority, whatever side that was.
