Context. They are dressed in Revolutionary times with Paul Revere as a main character. I think the reference is clear. While I wouldn’t put it past any public figure or company to ridicule conservatives, seeing an insult in this commercial aimed at a modern-day movement is quite a stretch.
The ad was put together by snarky New York leftists who graduated from Columbia and who think it’s great fun to insult conservatives. Sorry, I understood it just fine.
