Here is an article regarding the reaction to Manal Al Sharif's speech. Remember Manal is an individual with the right to speak to her individual perceptions. She is a woman who cannot drive, nor vote, nor leave the country, nor work, nor get educated unless her "guardian or owner" allows. She is dependent for her very movement upon her guardian's permission no matter how old she becomes. She is a woman who has been harassed, jailed and so much more. In her effort to free herself and bring her own perception forth she will be ridiculed and often times the worst offenders will be other women.
It is often times women who are the custodians and keepers of their female gender's imprisonment.
Remember who is it that often times forces their daughters down to undergo a Female Genital Mutilation (FGM) or to strangle their daughter as they need to have sons? It is most generally women. Women are the first to uphold imprisonment, torture, hatred, against their own and demand that they be silenced. They demand the status quo to their own detriment of human rights; all the while men are happy to let them do the dirty work of keeping women right where they want them, quite, obedient, and caged.
This is an excellent article that provides some insight on the reaction within Saudi Arabia.
