Apparently my denunciation of Venezuela-based Citgo has provoked the terror-sympathizing Stalinist company to withdraw from the Missouri market entirely. Good. The stations have been replaced by ZX stations, which don't have a website anywhere I can find but are supplied by J. D. Streett & Company, Inc., a Missouri-based company.
On another note, I just learned that Royal Dutch Shell does billions of dollars of business with Iran, so I won't be filling up at Shell stations anymore.
Does anyone know of any other oil companies that support terror or tyranny and that sell their gasoline in America?
