“No research has conclusively established….” seem like the most relevant words in that paragraph.
“I heard a talk radio show once. Extrapolating the comments by the callers is a valid and reliable scientific approach“.
“By pronouncing the letter H in the way that you do makes you responsible for the extinction of other languages“.
“…and, not content with driving other languages to extinction, you are also responsible for historic and current violence against minorities“.
“Sinister. Yes, it may seem harmless but you’ve killed other languages and dealt violence on the innocent with your language pedantry, you monster. Look at what you have done. Happy now?”
