"...or do we need to check what each and every person posts before sharing an opinion on what was posted?..."

YES!!! I think we all ought to do exactly that."

I tend to trust what others provide when a quote is provided or referenced..you and I apparently differ in this regard.

With that being said, if I ever provide an excerpt from an article or reference (typically I provide the full reference..but only do so if in a rush or I am unable to copy the full text due to technical limitations) I will provide a hyperlink such that you can see the full context for reference.
