I think that you're making two mistaken assumptions. First, you're assuming that everytime someone says 'such-and-such sucks', they mean it seriously. A lot of it is just old-fashioned posturing. Second, you're assuming that because a user on the site says that such-and-such sucks, the general consensus on the site must be that such-and-such sucks.

I don't think it's true that "Among the highest doctrines of Perlmonks is that the use of Perl and UNIX are superior to almost any programming language and operating system available." That belief is undoubtedly held by many members of the site, but it's not a tenet of the site itself. :)
