I for one welcome anyone that has a question about something they saw on the "news" or FB or anywhere else for that matter. It's helpful to know what, if any, BS is being spread and it also helps to get good sources so we don't inadvertently spread BS.
It's so difficult now to just say "oh wow, didn't know that" without accidently listening to some BS.
I've always been critical of things people tell me. Repeat some BS and get called on it once and it sticks with you. I've done it a few times...if you can believe it.
