Both you and pmontra above are completely misreading thaumasiotes's comments in a knee-jerk reaction. They were simply paraphrasing the intent of the quote from Trajan... If you have an issue with it, bring it up with Trajan.
> Women getting together is fine. Not once have groups of women ever been known to rebel against the government.
I agree with the sarcasm. Women are generally less problematic than men but they rebel when it matters. Another example, Rosa Parks.
Would Trajan have known this? Of course.
Compare your descriptions of suffragettes' terrorist activities with the research on how effective terrorist campaigns are at even getting their favored policies implemented. (And then, of course, ask yourself whether Trajan could have been aware of a 20th-century women's movement.)
