 ::The hat note as it is written is taking on the role of lead in which the article topic should be described, defined or given context in accordance with Wikipedia:Lead section. The way the lead has been written using statements of opinion that are not sourced is just not acceptable - hat notes are not supposed to be used as commentary on the article subject. In answer to Jaymax, I recomended using the source cited above in the lead, although this does not solve the issue of inclusion criteria, as CurtisSwain says.  |
