Just want to add my 2 cents on Agudat Yisrael's "condemnation":
Agudat Yisrael would have been just as good by condemning violence in the name of God, as that's clearly assur and a Chillul Hashem. Instead, they added extra, extraneous paragraphs, that serve more as a red herring. TZNIUT IS NOT THE ISSUE!!
The Sikrikim have decided to wage war on the rest of the Jewish people, not unlike the original Sicarii (for whom they take their name). Remember that the original zealots helped bring the downfall of the second Temple, and were heavily condemned for their behavior long before the destruction by Rabbi Yochanan ben Zakkai, one of the foremost Jewish leader, and a Tanna of major importance. So it's not without precedence to be utterly repulsed by the actions of the current Sikrikim, even if you are a member of the Charedi (ultra-Orthodox) world.
The most important thing to remember is that the Sikrikim in no way represent what true ultra-Orthodoxy is about, and CERTAINLY do not represent religious Jewry or the State of Israel.
They take whatever issue they can in order to terrorize the population. We must not get sucked into the idea that this is about tzniut or women. Many times in the past this has been about hundreds of other issues. And if we don't act soon, there will also be many times in the future.
Here's a small sampling of other issues that have been battle-cries for the Sikrikim:
