I'm making statements about absolute numbers. If something like 80% of google employees as a whole are democratic, and 80% of DC techs are conservative, then what you said about regional differences is true, however your claims about the ideas you dislike being held by a small but vocal minority would not be true.

The specific claim I'm addressing is the one that you made and that dekhn echoed, that these are the views of only a minority. To give an extreme example, extrapolating from the opinions of DC techs wouldn't make sense if google employed only a single DC tech.
