Teddy was fond of saying "the cause endures, the hope still lives, and the dream shall never die" to rapturous applause from the liberal multitudes. Is this but an empty phrase into which the hearer could place his fondest wish?
I'm sure you're right.
I personally know some liberals who are not politicians, and if I want to stay on speaking terms with them, I don't discuss politics.
There are also liberals in my family, and it makes for tense times during holidays, graduation parties, etc. if politics are brought up.
You cannot reason with these people, no matter how smart they are. So you end up talking about the weather, movies, food, or sports.
