I don't care if the statement was supposed to be a "joke." Decent, reasonable people can disagree on policy, but they do not wish extinction on political opponents. You don't say, "Gee, I wish I could just disappear everyone who doesn't agree with me." How many eggs do you want to break so you can make your leftist omelet? Millions of dead kulaks would like to know.
You remember this earlier post? I'm way beyond disappointment now. I am in a towering rage. I don't think I can actually be true friends with people like this. I can be a courteous classmate or colleague or co-worker or whatever, but I don't think I can really be friends with someone who spews political hatred. Needless to say I've never told this person what I actually think.
