Kind of moot to suggest it... I'd bet it's already happening as a grass root movement, same as it did for Exxon 21 years ago.

I'd bet "most" people who were outraged 21 years ago still avoid buying from Exxon today. The number of Exxon stations throughout the country is probably small compared to any other "big name" brand.

Don't forget to also eschew US Gulf stations, all those Arco outlets (AM-PM) and AMOCO branded gas outlets. I believe those are also currently BP owned brands.
