That may be your opinion, but in terms of accuracy you owe it to others to tell the truth. Thus you should state that the confederacy received at least one foreign nation's recognition rather than denying it all together.
Even the Museum of the Confederacy did not state that a nation had recognized the Confederacy.
I have emailed them on the issue.
Until then, if you have a complaint, it is not only with me, but with a number of other historical sources that do not mention this 'recognition' as such.
