It's a dumb joke that has no basis in reality. Faced with a life and death situation, party affiliation has no bearing and animal instinct takes over. Any man, dem, rep, socialist, communist, fascist, peasant, cast member, whatever, would fight to the death to save his family.
It's human nature to put down others to make your self, and what ever group you feel a part of, feel superior and justified in your thinking and actions. It's been going on for millennia. Every group does it. The unfortunate result is that generalizations and stereotyping occur and in the minds eye, perception becomes reality for the poor sap who's fallen for the propaganda.
If you find a joke about confused, weed smoking hippies disturbing, then go read some jokes about mullet wearing, dixie flag waving rednecks until you feel better. You can't take these things too seriously because they will always be with us.
If you look at the big picture, we have bigger things to worry about and we shouldn’t waste too much energy on stupid jokes, no matter what party they make fun of.
