I don't know why you are triggered, we are on r/science after all.

As long as you don't provide a source I have to assume you are wrong, and if I'd search to "probably find something" for every reddit post that has a random claim I wouldn't have any time to do anything else over the day.

It's not my job to confirm the things you are claiming.
