I think the phrasing is fine. It's self-aware. It acknowledges that stupidity, like beauty, is in the eye of the beholder.

"Looking stupid" is not the same as "being stupid." It could be very smart indeed, depending on your circumstances, to learn an additional language, and the point being made is that when going out in public and speaking it in front of native speakers, ridicule is not unexpected, and should be embraced.
