I don't know many Jewish blogs. Our admin, Lisa, has a blog and she also runs the Jews Against Obama blog, and she probably could tell you of other ones. And another member here, horselady, has a blog.
I live in Israel so I don't know about UK organizations, and I doubt if there are any. However We have in this forum people from the UK like Yesha and q_q.
I am afraid the liberal Jews are in control of the Israeli government, the Jewish media, and most other Jewish organization. You need to make a distinction though between the self hating traitorous Jews who act against their people deliberately, to most other liberal Jews who are misguided and passive but they are loyal.
The traitors should be exposed and cut off from the Jewish people, the rest of the liberal Jews- we should show them a better way, hoping they understand that they were mislead.
