Plus, there is an obvious bias in those results.

Suppose you know 20 BLs outside of this forum in total. You know that 3 of them qualify as B. You have discussed this with 2 others and they both qualify as A. For the other 15, you have no idea. Thus, you come to this forum and you count the 2 A that you know of, and the 3 B that you know of. Yet, for all you know the other 15 people all belong in the B group and the true count should be 2 A 15 B. There is an enormous discrepancy between those two counts, caused by the obvious fact that you are far more likely to get into a discussion about these issues with people for whom it is an issue. To balance that out, you could count all those for whom you have no idea as being in the A group, but then you might be counting incorrectly because how many of them actually did have experiences and you just never got around to talking about that? Furthermore, the kinds of people each poster here relates with may say more it does about them than it does about all of us as a group.

Counting people from beyond this forum is problematic for many reasons and makes any results you get useless.
