A recent post made me remember a Ayn Rand concept that I found pretty powerful in the past. This concept is called "anti-concepts", and is defined as:
Some terms that she considered anti-concepts were: consumerism, duty, ethnicity, extremism, simplistic, open and closed mind, isolationism...
Are there new anti-concepts that you can think of that has have been introduced into the lexicon since Ayn Rand's days? One that immediately comes to my mind is "Islamophobia".
