Why be so formalist? We are talking about food, so it has a place here. I don't feel like going back to that thread again ...
Timothy 4:1-5 does not explicitly say that animals are created as food. It just says we cannot forbid anyone to eat but what is food? Paul explains in Corinthians 8:13 that he had to quit eating meat in order not to scandalise his "brothers", thereby assuming that early Christians were vegetarians (confirmed by several sources) and probably so was Jesus (not just pesco-vegetarian as He's sometimes referred to).
Why the anti religious vegans are hypocrites is just because if care for animals is really their ideal, their attacks against religion is at the same time an attack against the main obstacle to mass consumption of in particular meat. It's just a mixture of hypocrisy and stupidity, there. The 1970's which were anti-religious years through and through were also years of a consumerist boom because the war and privation years of the forties and seventies increased Euro appetite tenfold. So gluttony was the standard, as illustrated by the horrible though interesting film La grande abbuffata by Marco Ferreri. Churches emptied but supermarket filled in. Nobody wanted to hear anymore about the Lent, about fasting, about meat prohibition on Fridays, etc. So as a Catholic I have no moral lesson to receive from atheistic vegans, on the contrary. Until the sixties/seventies common people rarely ate meat. It was not just because they could not afford it, it also was a habit. When they ate meat, it was often out of necessity, because there are regions like here in Belgium where nothing grows in winter. Nowadays, everybody wants his own hamburger, his hot dog, his underdone steak which here on the Continent is more the result of an Americanization of the ways of life than of tradition.
Religious people defend a natural order based on common good. Atheist opposed to it an order based on individualism or general interest (which is the sum of every particular interest) in which society is made for everyone to satisfy their endless needs and desires in absolute freedom. No wonder that in such an order, meat consumption and animal slaughtering gets huge. In order for veganism to prevail massively it needs a religious revival, a counter-revolution. A restoration of traditions, of authority, if only at school because it has to start with education, kids have to understand that they cannot always get what they want. And a restoration of discipline and fighting against oneself.
