Pages such as "Women bringing you Sandwiches" and "Keep Ya Pimp Hand Strong" clearly violate Facebook's TOS (See https://www.facebook.com/communitystandards). Both pages "[target] based on gender" and one explicity advocates domestic violence against women.

Examples of racist pages include "Lazar Kaganovich" (the sole purpose of which is to attack the USSR official because of his Jewish ethnicity) and "N***as be like" as well as its compatriot "N***as/B****es Be Like." (which is both racist and sexist).

Why Facebook refuses to remove these pages is beyond me. 

Why Facebook also refuses to remove other hateful content (such as abusive photos and comments) is beyond me.
