point of logic: caring about treating something humanely is an implicit acknowledgement of its moral significance and ergo incompatible with a mindset that endorses its slaughter.
The people that push for more humane conditions for slaughter or whatever are people that understand that the world wants to continue eating meat. Minimizing the pain and suffering that these creatures experience is a step in the right direction, in a world with fewer options.
Now, personally I believe that cattle are morally non-significant in the sense that it is absolutely okay to consume them for food. At the same time I believe we shouldn't needlessly torture them any more than necessary. It's a compassion thing I guess, though the hard truth is that these animals need to die in order to be harvested.
Now, could the human population be fueled entirely by vegetables? I doubt it. Many parts of the world are still struggling to feed their populations. Removing meat from the menu would be a bad idea. Your lifestyle may work for you, but it doesn't easily extend to the other 6 billion people on the planet.
In a morally ideal world sure, we wouldn't kill animals for food. But... that's not the world we live in.
