This page does not advocate any violence, or the breaking of any laws. It is, rather, an exercise in Free Speech.
It also asks,
Is Miri Mogilevsky, who blogs at Brute Reason at Freethought blogs! a loyal American ?
Has she ever had sex with PZ Myers ?
Has she ever had sex with Rebecca Watson ?
Because, obviously, all of those are offenses that warrant execution. It’s revealing, though: this is a person who does not understand the concept of free speech at all (it is not an idea that encourages harassment or intimidation), and also has the usual anti-skepchick/ftb obsession.
Anyway, as Ophelia suggests, if you have a facebook account, go to the page, click on the the gear icon just beneath the cover photo at the top, and select “report page”. As a bonus, you’ll discover how pathetic Facebook’s reporting mechanism is!
