The correct interpretation for most people is "I bought my car because it was a good car and now for reasons beyond my control it may appear to be a political statement. Also sorry for giving that guy money, I didn't know he would spend it on Trump."
I understand you don't think it's a good car, which is fine, but most people who bought one did not agree with you.
Your comment is a little confusing because you obviously understand this concept, you bought a Prius because you thought it was a good car, not because of a political statement others may have projected onto your purchase. The same is true of most Tesla owners.
