In the past, whenever there was discussion of the possibility of peace negotiations leading to a withdrawal of Israeli presence from territory to be given over to Palestinians, Haredi leaders would justify the Haredi presence in such territories as being different than the style of the presence of the general settler community.

While the settler community is largely found in towns and villages throughout Judea and Samaria out of ideology, the haredi towns and villages are there not out of ideology but due to the low cost of housing. They would then use this justification with both the government and the Palestinian leadership to try to ensure that Haredi areas would not be included in any withdrawal.

All that is changing now. The haredim are so upset with the Habayit Hayehudi people, for their involvement in the shivyon bnetel law which will presumably bring about the drafting of yeshiva bochurim, that they are willing now to even give up their own houses in order to promote the idea of an evacuation of the Israeli presence in Judea and Samaria.

"Hundreds" of residents of Haredi towns such as Beitar Ilit and Modiin Ilit have drafted a letter and sent it to the prime minister, Benjamin Netanyahu, in which they voluntarily offer to be evacuated in the event of a peace agreement. They explicitly say in the letter that they offer this support for a deal and would voluntarily evacuate because of the "decrees" and the criminal sanctions imposed upon them.

While they think they are taking out revenge on Habayit Hayehudi, they somehow do not realize that Habayit Hayehudi does not own the country - their offer is to give up Eretz Yisrael because they are upset at one group of people. If this was their ideology, peace at all costs, that would be consistent and fine. However, because it is not their ideology, it is just spiteful stupidity.
