The progressive movement, and the activist base of the Democratic Party, creates and supports venues that demonize and defame the Jewish state, thereby also creating hatred toward the Jewish people.
Among political blogs such venues include Daily Kos, the Huffington Post, and the UK Guardian.
These venues do not generally criticize Israel, but dehumanize that country.
For this reason, among others, the progressive movement, and the activist base of the Democratic Party, undermines the well-being and safety of Jews around the world, sometimes resulting in violence toward us.
Therefore, as a matter of common sense and basic human decency, Jews should leave the progressive movement and the Democratic Party as we seek to build alternative political structures that are not home to toxic anti-Semitic anti-Zionists, who would see us robbed of self-determination and self-defense.
Let it also be noted that the above does not necessarily represent a consensus among people who participate here, include the frontpagers. It strikes me as an entirely reasonable argument and conclusion, despite the fact that many people would consider it more than a little contentious.
