As a thought experiment, let's say someone started claiming that car rides are a significant cause of suicides, and pointed to anecdotal cases where car rides were involved in a suicide. How would you disagree with them without either sounding callous about those cases, or saying something with the same meaning as "suicides are unfortunate, but"?

Sorry, but that's just a silly comment. There are many many things causing suicide, including things like celebrities dying or marrying. Should that now be outlawed?

Talking about suicide can cause people to commit suicide, should it be outlawed?

And there were books banned for similar ideas and society at large decided that in most cases it's overreacting and does more harm than good.

Yes, I'd do everything for children to not die, but I wouldn't want them to spend their whole lives in a padded room being only allowed to consume nutritional paste and essentially have no life at all.

There is that idea of laws shouldn't be made for individual cases. It's a bit like how many people believed things like rock music made people into murderers or suicidal only to now have lots of people claim it saved them.

There are people claiming that LLM systems helped them through harsh times.

I say claim, because I neither know all the details about those cases nor claimed suicides, but the idea of absolutes like that is a lot more bothering than what you quoted. And not being able to take (maybe understand?) nuanced stances.

Please, for the sake of everyone involved apply some critical thinking skills and read more thoroughly.
