Presumably...
...this one merits a mention because it styles itself as "The Alternative Encyclopaedia" and would appear to be attempting to present itself as some kind of serious reference site (for those gullible enough to take any wiki article, or indeed any other web item, without the appropriate dose of salt).
Under those circumstances, this one arguably becomes more of an issue than a.n.other looney-tunes site that wears its political bias rather more openly on its sleeve. Not that there's anything wrong with political bias per se - that's where the whole free speech things comes in - just that such political bias should at least be obvious or easily deduced.
Something like that anyway.
