Oh good...a count discussion.

Short answer: Yes. But I will expand (and try to stay within my boundaries)
While I won't say "brainwashing", in my opinion Flash and Three have far more influence than they should over other players, especially newer players in choosing a count. Norm's site in general has a disproportionately higher density of proponents of higher level counts than the blackjack community in general, and that includes what I call professional and/or serious level players. The fact is that the vast majority of serious/professional players play a relatively simple count, most hi-lo, or similar level one count or a level 2 count like RPC, or Zen with no side counts.
But on Norm's site, to hear these very outspoken and frequent posters tell it, anyone who doesn't play a level 2 count (or higher) with numerous side counts, or worse some sort of custom columns count, are talked down to, and told they can't make any money and as you rightfully described, made to feel stupid.
Flash has frequently said things like hi-lo is a weak count and/or no professional players play a level one count. Both of which are just flat out nonsense. Most professional players play a level one count. While Norm occasionally will say something about one of these flat out wrong and misleading statements by Flash, the fact is that there are not many "simplicity" proponents left at BJTF, so most of these statements go unchallenged, giving these members far more influence than they should have.
Now, if a player
really only plays single or double deck blackjack, that might be a rare situation to consider a higher level count. But, I have to wonder where all these members at BJTF, spread out all over the country and Canada are playing all this single and double deck blackjack? There is very limited single/double deck games in most areas of the country.

And as time goes on there will likely be even less.
