"God gave us animals to eat,so it's ok"?

You really need to read upon Noah and the great flood. Why can’t vegans put it in your activist minds that God oked one time to eat animals as the great flood happened they had to wait til things to grow a full year.

This is about the Temple that Jesus drove out of money changers.
The vendors, as they are called , or money changers were cheating people and taking advantage of them. They weren't just selling animals for temple sacrifice, they were cheating their customers. Jesus said they had turned the Temple into a den of thieves, when it should have been a House of Prayer.
