Fair enough about Facebook, I think you did the right thing! But I have already stumbled onto your link as a source for “gas stoves bad”, and it’s just not true.

This is part of the short abstract (from your link):

If kitchens are not well ventilated, benzene, nitrogen dioxide, and other VOCs may reach levels known to harm health.

I’d emphasize the If kitchens are not well ventilated so for me it’s as obvious as saying electric stoves are dangerous if the wiring isn’t well done. Or, gas stoves are not dangerous, like bicycles aren’t etc.
