...the right to get high with a friend in front of your kids. Choosing not to smoke a joint in front of my kids does not make me a slave. I don't think it is a valid comparison. I do think drug laws are immoral, but there are ways to oppose laws and educate people. Getting high with your friend doesn't accomplish that. It just gets you high, and I'm not sure what it teaches your kids.
Abolitionists risked jail to rescue runaway slaves. They acted courageously and morally to oppose immoral laws. Smoking a joint witha friend in private doesn't accomplish anything of the sort.
