 ==Correlation vs. Causation== 
 ""Educational attainment among whites has a significant positive effect on support for same-sex marriage"" This seems to confuse correlation with causation, an overall feature of the writing in this section. It seems unlikely that educational attainment can genuinely be shown to be causative here; much more likely is one or several underlying factors such as social class, general intelligence etc. This section needs careful rewriting."
