None of those professions is inherently evil (except maybe lawyering) but their opinions are far left of ours.
Still they're not as far left as the Earth Firster's, the most militant Greenpeacers, the Queers (though they like the gays), etc.
Some of them are even pro-Israel, or at least not pro-Palestine.
Most of them support the need for some type of free market. They just want to tax and regulate the heck out of it.
The thoroughgoing Marxists want to eliminate the free market system altogether.
There is a difference, and it is more than a dime's worth.
Believe me, when it comes to money, I’m spot on about Liberals. As a construction contractor, I deal with these people a lot. They are the love mankind, hate people types.
