Statistical Bias - Continuing With the Tel Aviv University Left-wing Bias

Here's a response from today, following up on the story about Tel Aviv University and its left-wing slant:

"We've been dealt a stupid blow with no justification," a senior TAU professor said yesterday.

He said Hativa's comments were "not based on a statistical analysis of an explicit question put to all the students, right- and left-wing. They were based on complaints written by those who want to complain. It's a statistical bias, and it's impossible to know how representative it is."

Another lecturer said, "The definition of left-wing is very broad. Until specific statements or situations are examined, these are nothing but generalizations that right-wing people would gladly use to attack academia."

I can fully understand he being upset as well as his research insight.

But how is it that the academics opposed to certain government policies get all the publicity, most of the grants, get invited to all the academic conferences, and are nigh worshiped across the globe but right-wing or nationalist academics are shunned, boycotted, despised?

Is that a statistical bias?
