It is a compliment and I agree with you. I think of it like this:
Well you can consider it the only valid reason of course, but that's not to say that others are obliged to consider it that also.
The desire to be humane about it is a valid reason to "postpone the deaths" of animals and let them have a proper existence according to their natural behavioral repertoire. Not in small boxes being force fed to drag their unnaturally fat, mangled torsos chock full of antibiotics as fast as possible to the meat cleaver. Simply the desire to be humane is in itself a valid reason because we are human and in very much a real way we do not get the choice, less so in any case than we get to choose whether we eat meat or not. That's why we put so much effort in hiding the practices and most people - in Western societies at least - know meat only as pink packages of neatly cut shapes in cellophane with cooking instructions, you'll find in a cooler at the supermarket. You can eat yourself sick in meat without ever having to kill an animal or when living in cities even have ever seen a live one.
So while there are sides to the equation that are not so simple, a humane treatment of animals - letting them live their animal lives, letting them eat their own food (e.g. cows don't normally eat corn, they eat grass and preferably wild grass with herbs that they look for in relatively small herds) before killing them and live out our parasitic urges on their meat, seems not much more than just normal human behavior. We can of course look the other way, think of clever reasons why we should, but in hurting the animals we eat we are hurting ourselves and the results show.
