A major goal for many professors is to enlighten their students concerning the deep hatred that all-too-many Americans have for outgroups like blacks and homosexuals, and that this animus is concentrated among conservatives. They see discrimination as perhaps the greatest challenge facing the country.
Typically, they document the hatred with rock-solid evidence like opposition to affirmative action programs.
In his book What Americans Really Believe, Rodney Stark reports the results of a survey of professors: 53% admit negative feelings towards evangelical Christians, and 33% feel the same about Mormons.
Imagine if a survey showed that a majority of some group have negative feelings towards blacks. Social science professors would interpret this as proof that the group would commit genocide if it could. Yet, this is exactly the state of affairs among professors with respect to conservative Christians. Projection is at work here: the real haters are the finger pointers.
