I think I can pick a Billy post before looking at the name... usually!
In regards to the serious post that you commented on I think that everyone is entitled to their opinion and if that opinion is - BMC taste like crap it doesn't have any bearing on how good a brewer they are, e.g.
"Experinced" brewer that knows how hard it is to make a American light lager - BMC taste like crap and even though I can make one that rivals the likes of Bud lite I will not for the fact that I don't like the style.
"Newb" brewer that doesn't - BMC taste like crap, why would I want to make something that I think taste like crap?
Both of them a valid opinions of BMC tasting like crap and neither make the person a better/worse brewer
