This is probably not the response you were looking for, since I assume you are asking people who converted to Catholicism from some other faith. In my case, I took the opposite path, from Catholicism to a more personal and fulfilling faith in Jesus. I did this by joining what most would consider to be a main-line Protestant denomination: United Methodism. However, the particular congregation that I belong to, while part of the great denomination, is somewhat more conservative than most other UM churches (at least in New England).
But to answer your question, not one person, officially or unofficially from the two Roman Catholic congregations that I was a part of earlier in life, including priests and nuns that I had as teachers through 12 years of parochial school, have ever questioned or criticized my decision.
