I only responded after you called them mentally ill. Your initial response was still a command to fix it, which is still being a jerk, but didn’t really warrant responding since it was pretty obvious that you were kinda trolling. Saying something like, “hey, your use of the thorn is obnoxious and makes it difficult for non-native readers and folks with reading disabilities” probably would have sparked a less adversarial discussion
You said they had a mental illness, which is being an ass and just not appropriate. Your replacement was not with established replacements though. You chose numbers that correspond to letters randomly. If you had done some l33t it would have correlated a bit better.
I get it, it is annoying to a lot of people. That being said, engaging and coming up with some salient points would have been a better course instead of going straight to being aggressive. People might not have been so keen to respond if that had been the case
The difference between what you did and what San does are pretty obvious. The thorn is an established character with a sound that has been associated with it for hundreds of years. Yes it is no longer used, but it is not a garbled mess of random characters like your example. It is a replacement of 2 specific letter with one character that represents the same sound they make. A little annoying? For some folks, yeah. Worthy of being a total ass about it? Absolutely not.
the results of current study suggest that blindness does not protect against schizophrenia.
This statement read to me as suggests in that more research is needed. It suggests this thing, but to definitively state we need to do more
From the linked paper (bolding mine):
Conclusions
The relationship between schizophrenia and congenital blindness is still unrecognized and controversial. Several studies are done in this neurodevelopmental field but so far there has been no assertion nor confirmation of the suggested hypothesis. More research is needed.
Which is a more concrete version of the conclusion from the study linked from rain_enjoyer.
Correlation is not causation.
I often do because they are the only person I’ve seen use and I don’t interact with them much. Not to mention non-native readers and people with difficulty reading. I get the intent behind it, but at this point it seems like throwing a wrench into a tornado.
