Theres no straw man arugement here. The fact is everything is on the internet. Telling someone their ignorant because its on the internet is a half truth. Its like saying I graduated from Harvard and therefore I had the best education money could buy and theres no way i'm ignorant. The straw was the ignorant comment and not providing what it is why it should be celebrated by Americans.
Nah it’s really easy to understand Juneteenth if you just google it. Let’s not argue on the fringes of the subject and claim it applies here. Ignorant people always have excuses for why it’s too hard to become educated on a simple subject.
Wikipedia is reliable enough to lookup what Juneteenth is, if you were really curious and not just complaining about the name.
