social justice, tolerance, social market economy, free trade, economic freedom.[74][75] " Yessiree, I'm a liberal!...
Hmmm. Somehow "free trade" and "social market economy" just seem so...oh, I don't know...antithetical. "Free" of course meaning free, and "social market economy" meaning governmental controlled assets, targeted economic redistribution, and statutory restrictions on "free trade". "Social justice"? Just a PC term for socialism.
Being a liberal and being a socialist are two stunningly different beasts, django1. One espouses fair social causes, the other Marxist government. The latter is not the cup of tea of many, including "liberals", who still believe in the fundamental laws of this country, including the Bill of Rights and the U.S. Constitution, and I think many of us still prefer "free market" capitalism and true freedom to Marxist dictatorship of the proletariat and nationalization of the economy.
But besides all that....you completely missed Alex's joke. I'll let you figure it out for yourself...but a hint...it has to do with the "dis" part.
