Those women do not aim to follow the laws of G-d nor do they aim to serve Him. If they did, they would follow all the laws that apply to women. Just a look at them reveals that they are not interested in serving Hashem. Some are deform Americans who go to Israel just for this purpose while others are liberal Israelis. All dressed like men, so already broke the laws where a man must not dress like a woman nor a woman dress like a man. They keep Shabbat? Only they know if they do but it's possible they may not really care about it. How many of them keep strictly kosher?
It's only when they aim to cause discord that they attempt to pray. Which makes them hypocrites. To internally not follow any laws but externally do it when others are looking is what makes them sick hypocrites. The moment someone tries to do a mitzvah for the wrong reasons, for the reason to be seen doing it, to do it to cause controversy amongst Israel- it becomes completely invalid. And actually a Chillul Hashem.
I only hope that one day, I will be there to tell them that they are not representing me. I honestly think that we women (the religious ones) need to deal with these liberal females by blocking them ourselves. The army can kick them out and arrest them but it remains seen as "government oppression". But if we women come together as a whole and block the path of these women, it will send the message out that religious Jewish women are NOT in favor of these liberal females creating a show of hypocrisy at the wall. Let us pray in peace and modesty and take your show someone else! The strongest message to these females is seeing that women are not going to allow them to do this anymore. If only the religious women at the wall would think of doing this next time!
Create a human chain and block their path!
