This portion of the week starts with the Temple Sacrefices; what would they have to do with the first word of it, Va-yikra?
Rashi tells us (Leviticus 1:1) that G-d Yiker, happens upon the prophet of the Gentiles (Numbers 23:4), but Yikra, spoke to Moses. Kuf Reish, kar, cold. G-d is warmer with His Jews. Alef added: better than without. Beit added (instead of Alef): even better communication: us bringing Him Korbanot, offerings.
Abraham says: stop sacrificing your children (Leviticus 18:21). As last part of his training to start heading the Jewish People, G-d asks him to sacrifice his only son (Genesis 22:1-11). Egyptians worshipped lambs and kids. Just before leaving Egypt, at the birth of the Jewish People, G-d asks us to sacrifice them (Exodus 12:3). We commit a terrible transgression, worshipping the Golden Calf (Exodus 32:19). At the opening of proper communications with G-d, He asks us first of all to sacrifice a bull (Leviticus 1:3). A sacrifice must shock.
I had dozens of good reasons to become a vegan, but my decision was sealed when I thought about the animal sacrifices in the Third Temple, may it be here soon. I for one am not looking forward to rivers of blood coming out of the Sanctuary. However, how could the Rabbis modify most of these offerings (Learn about them, see them in a 3D movie, repent) preventing the daily ritual slaughter of thousands of animals if people eat meat all day long every day resulting in thousands of times more dead animals? G-d should not be offered less than a tenth of a percent of what humans freely and happily consume?
Another point. We don’t have capital punishment anymore because for two thousand years, it doesn’t deter anymore. So maybe we can also not reinstall animal sin offerings because they do not shock anymore. Could it be that the only ones allowed to bring animal sacrifices will be vegans and vegetarians?
