“Context”
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.
Probably not, but whatever. Sometimes a cigar is just a cigar. Context is always key. If you have to do “research” to find out who’s behind an ad in order to prescribe some “other meaning” to what they’re doing, chances are it’s a case of straining at gnats and swallowing camels, but whatever. Be offended if you like. I’ll see it for what it is — a historical reference. Nothing more, nothing less.
