Nope. Mansplaining is defined as: the explanation of something by a man, typically to a woman, in a manner regarded as condescending or patronizing. It's especially galling when the woman has direct knowledge of the subject whereas the man has formed his misinformed opinions by searching the internet.
Comparable for you: having a Lutheran woman (for example, me) telling you what Catholics believe. "But the internet says it so it must be true!"
