"[The word class has] been excised from the acceptable political vocabulary, except in the limited usage of right-wingers when they accuse liberals of inciting 'class warfare' - a charge that means it's okay for rich people to vote their economic interests but it's not all right to encourage poor people to do so."

Further, in writing, I feel corrupt and unethical if I have to look up a subject in a library as part of the writing itself. This acts as a filter--it is the only filter. If the subject is not interesting enough for me to look it up independently, for my own curiosity or purposes, and I have not done so before, then I should not be writing about it at all, period. It does not mean that libraries (physical and virtual) are not acceptable; it means that they should not be the source of any idea.
