...and not one penny of that came out of my wallet I am happy to say.
Have you never heard of “unbranded gasoline”? Just because you’re not buying gas at a Citgo station (which is almost certainly privately owned) doesn’t mean your money isn’t going to Chavez. And, besides, oil is a fungible commodity. If you don’t buy Venezuelan oil and use some other oil instead — let’s say Canadian — you’re consuming that Canadian oil and freeing up Venezuelan oil. Someone else who would have otherwise bought that Canadian oil will then just buy the Venezuelan oil that you freed up.
Let’s face it: oil’s fungible, and the biggest producers of it tend to be our enemies.
