"For example that BP's response in the Gulf shows a greater commitment to the small people than Union Carbide showed in Bhopal or Exxon Mobil in the Niger Delta? "

That is a perfect example of an irrelevant appeal. These disasters have nothing to do with each other. You are merely attempting to make BP look better than Union Carbide and Exxon Mobil when the topic has absolutely nothing to do with Union Carbide or Exxon Mobil.

This is also an example of your dogmatic defense of BP by bringing up companies that are American owned or associated in an attempt to make BP appear to look better. Let me be clear, these two companies have not taken proper responsibility for two of the worst man-made disasters ever. They also had nothing whatsoever to do with the BP disaster which is the topic at hand.
