Is there open hostility to animal rights? I meet that sometimes with Christians, however is to take animals into moral consideration frown upon? and in an unrelated note are they many Vegan Jewish dishes?
In the
haredi (ultra-Orthodox) world, there is not necessarily an open hostility to animal rights, per se. But you must understand that for that community, they deal with the world as entirely through their own interpretations of Torah as possible. They shun all secular philosophies and worldviews as much as they can. The issue for them would not actually be a hostility to treating animals well-- as I mentioned, there are ways of interpreting Jewish Law, even in the Orthodox world, that encourage such behavior-- but to embracing a secular philosophy. Even if they were to come to such conclusions through Jewish Law and Torah study, though, the result would probably be a compromise position. For example, Rabbi Abraham Isaac Kook, first Ashkenazi Chief Rabbi of the State of Israel, was mostly vegetarian, and ethically desired to be entirely vegetarian, but, due to the constraints of custom and tradition (which encourage eating meat), compromised by only eating small amounts of meat on Shabbat (the sabbath) and holidays, or at weddings-- occasions when we are encouraged to eat meat as a sign of indulgence and festivity. And Rabbi Kook is, these days, considered fairly far to the left in Orthodoxy; his kind of compromise might well prove insufficient for many modern
haredim.
As for vegan Jewish recipes, I'm sure there are, or there could be, even if not by design. There are many Jewish cultures, and many varieties of Jewish cooking. Most Ashkenazi (European) dishes either contain meat or dairy, but not all. I have had, for example, various kinds of
tzimmes (stewed fruit compote) that do not contain meat. There are more likely candidates in Sefardi (Iberian) or Mizrachi (Middle Eastern) dishes. I have had, for example, a Yemenite lentil soup made without meat. And some kinds of
minas (a matzah casserole made by both Sefardim and Mizrachim) are made without meat, and could be made without cheese or eggs.
But it is deeply unlikely to find vegans in the Orthodox world. That is simply foreign to them. In the
haredi world, you're not even likely to find vegetarians. They would probably consider it secularism, to be dismissed.
