Transcript
A threads post saying "There has never been another nation ever that has existed much beyond 250 years. Not a single one. America's 250th year is 2025. The next 4 years are gonna be pretty interesting considering everything that's already been said." It has a reply saying "My local pub is older than your country".
My country is 900 years old and my people has inhabited these lands before the romans ever dreamed of set foot here.
That is plain ignorance.
