Have you been on the internet lately?
Well exactly. I was thinking that in my first days online in the 90s someone posting either:
The USA were rather late to WWII (7-ish words)
You'd all be speaking German if it wasn't for us (10 words)
Was enough to derail many online conversations. And a well placed "Fake News" or "Bollocks to Brexit" is pretty effective nowadays.
"Look, I came here for an argument!"
"Oh sorry. This is abuse. You want next door."
