Even an answer of the form "here's a set from a quick DDG" is more productive, and might even teach the commenter something, as it provides a fixed (even if incorrect) basis for discussion.

Given the option between not commenting at all or offering some variant of JFGI, I'll strongly prefer the former. "You don't have to attend every fight you're invited to", or comment on every post. But if you do, try to land solid punches. Even if you're not Mohammed Ali.

(I've frequently learned things, and more than once entirely changed my mind, in researching to answer comments.)

That first google link is shit.

has been isolated the alkaloid d-turbocuarine, which is used to treat such diseases as multiple sclerosis, Parkinson's disease and other muscular disorders.

It’s a muscle paralyzing agent used in surgery. It’s not use in MS or Parkinson’s.

I wonder what else is wrong in the article.
