@JBennet Fine to publish it, but within that article (and others that you want to counterbalance against others) should be a sidebar explaining that and where to find the other argument.
Additionally, opinion pieces that state facts to support the opinion should include fact-checking.

@JBennet Even letting the incorrect facts remain in the original piece, having the fact check as a sidebar would be good.
Do this for pieces from any side of a particular issue.
