It's an internet forum, not an academic journal. Water tight arguments are not needed. If one wants to call bs, they can just do it, no need to dance around the topic by asking for a citation.
The person asked for citations, leave it be, stop dudexplaining how Internet works for you please.
I call bs on your 2 comments.
Even when people sincerely ask for a citation on a debatable topic, on an internet forum, it's effectively saying "I won't be hear any opinion that doesn't match my own unless it's as water tight as a law of physics". Another form of this is "show me the data".
