thanks for the sarcasm. Do u have a toddler i can use to test your theory?
This is not a sarcasm, but the truth could be as plausible as it is. If you feel it is a sarcasm, so be it

There is no need for anything to be proven. It's just what you wanna feel it is. Be safe and avoid the truth is a possible scenario. Be safe and it's correct is also a possible scenario. Both are just true and also false until you know which is more true using reasoning.
If you believe in hearsay and want to be fearsome that it might be true, then it's the same as how fearful it is to believe your soul can be suck it. Can you prove each open of the shuttle does not take away 0.1% of your soul ? Or do you believe that soul doesn't exist ? While I'm scientific, no science to date can prove soul and god does not exist, at most scientist can only tell you they can't be sure but the probability is low because of non-existent evidence to indicate so. If you believe in science, then you will also possible there is a possibility that should exist no matter how minor it can be.
Here you feel it is a sarcasm that why I use such a claim is not probable. That's because you choose to believe soul cannot be taken into a camera, and you choose to believe the probability is low. Then it makes no sense to believe a hearsay that flash light will damage a baby's eyes despite there is no reported cases that can be authenticated to date.
On the other hand, I can find numerous articles that says it's safe.

I can find more, but there is sufficient to get my point across. We know Internet sources are not completely trustable in this context. You can also find articles that says it's harmful.
The question therefore is, does play safe has anything to do with truth. You can definitely shoot your kind of question "Do u have a toddler i can use to test your theory?". That doesn't answer at part of the question, except posing a threat of "would you do harm to your baby". But the important suffix to the threat should be the following "would you do harm to your baby, knowing the the fact .... " However do you know the fact to perform an informed decision.
Thus, there is no sarcasm at all, it's just how you want to take it.

No need to get agitated with your shooting back of that question. I have long anticipated it when I wrote that earlier post, just that it took you so long to response only. lolx.
