"well I think if you block foreign anonymous posters peddling a view that isn't mainstream"
again, you're sounding like an anti-vaxxer
"mainstream" refers to publications where the author and the company they work for are known
"alternative" sources are often anonymous and you don't know what company they work for or even what country they are from
" Why you would think ridiculing people might work beats me - work how?"
it may not......some people when seeing that they are following information that originated on a troll farm in Bulgaria may change their view.....others will not......it's their choice
information is proving to be a as dangerous as some food and supplement products.......there is legislation to ensure the source of such products is know......why not apply the same to information.......?
