I have not been snotty. A lot of people read these posts, and I was trying to explain that the list is correct as to certain listed denominations which the Catholic Church considers having invalid baptisms. However, identifying those accepted as a low number is an incorrect reading of the list which you posted.
I have had to deal with the issue on a real world basis. And I used diocesan information, just as you did.
Evangelicals, being the one example I picked out, do not have a structure as tightly organized as do, say, Jehova’s Witnesses, or Seventh Day Adventists. Just as “Bible Churches” and Fundamental Churches" get somewhat lumped together, they have a far looser organizational structure and continue to engage in dividing and resulting in new churches, which is why we have an estimated 30,000 to 35,000 churches in the US.
For example, there is the “Evangelical Church of North America” had 133 local churches as of 2,000; but the fact that some church down the road uses the term "Evangelical " in their name has no particular reference to the ECNA; it is rather a generic type of name separating it from, for example “XYZ Bible Church” and the many permutations out there.
Anyone can get a degree from a bible college and set up a church; they may or may not have some formal or informal process of “ordination” or “calling”. A friend of mine when I was in grad school was going to start a non-denominational church as he styled himself as a “bible believer”, and he was by no means untypical. He was attending a Presbyterian college but was not studying to be a Presbyterian minister.
