The difference between common and unholy

I have been thinking about my following of the food rules in Leviticus 11 this week. I guess that I am still surprised about how many people react so strongly to my decision. In Acts 10 and 11 Peter uses two Greek words koinos and akathartos.

If it were possible to prove beyond the shadow of a doubt that the food laws are part of how God wants those who believe in Him to live, would people just change their eating habits? I doubt it. There is already so much which is so clear and yet people do not follow God's words.
oh well what can I do about it?
