While reading about inert gas asphyxiation for animals it brought up the introduction of using argon and nitrogen from now on. Nazi doctors used pure co2. Veterinarians and doctors have since discovered if you use argon or nitrogen it is a painless death. All I was saying is that information changes over time. What might have been done in the past is no way what we shoukd do now. I support inert gas asphyxiation if the proper elements are used at the right ratios. I wasn't just trying to bring up Nazi for shock value. I have been looking into this for days. When the original discussion happened in started reading endlessly to figure out if what I thought was true or not. I love being wrong. That is just a chance to learn about being right.
