Please don't fall for smoke and mirrors. This is Shas clearly pandering to religious voters. This is their outward measure to pull the wool over your eyes further that they are a 'religious' party. They make bigoted anti-gay statements, guaranteed to make headlines, and religious Jews in Israel sitting in yeshiva get the further impression that these guys are religious, go back to their sefer, and will vote for them next time, since anti-gay rhetoric must mean they are committed to Torah right? They are trying to maintain a base of support in the face of their Left-wing SECULAR party activities. The haters of gays also eat this stuff up and thump a midrash or Talmud aggada as giving Shas legitimacy in their wacked out comments. Come on, you should know better. Perhaps it is Shas's willingness to divide Jerusalem that is causing the Earthquakes in Israel. That would be far more likely.
Shas is a political party and those making this statement are knesset MK's. They are open to criticism of political decisions and statements on the public record. Ignoring everything else we know about Shas and disregarding the current political climate, everything else a level playing field, the comments are irresponsible at best.
