The best way to get out of jury duty is simply tell the judge you have a biased point of view, can't work well with others and are discrimatory. I remember serving jury a couple of years ago. Everybody was in the room initially. The attorneys picked people. The Judge asked "if anyone here believes they can't serve jury please come up and state your reasons". A couple of people came up. Actually quite a few. When the case finally finished and the judge came into the jury room to thank us.
One of the juriors asked why would of disqualified you or what reasons were valid. She stated if someone said to her, that they were discrimatory or biased she automatically removed them...
