Maybe not every university., but the trend is what it is. You are in effect being dishonest by ignoring or denying it.
All schools of social science are leftist. They do not permit dissent. Does that make their policies correct.
I submit that dissent is not permitted, consequently, the trend is meaningless. Saddam won 100% of the vote when he faced election. He also did not permit dissent. Did that make him the people's choice?
I would rather see Evolution strengthened as a theory by having serious, funded scientists and researchers trying to poke holes in it and find inconsistencies in it.
Physics has made great strides in the past 100 years because many competing theories were proposed and argued by competent, funded people. Some right, some wrong! Understanding of the "origins of species" (in my opinion) has made far fewer advances because it has become a religion and heresy is not permitted.
