I think that some new editors are being made to feel that they are not part of the established WP community and consequently they are "acting up". This is the same "old hands" vs "young Turks" divide I see on other sites and indeed in real life. This is not to say that all old hands are pitted against all new arrivals, but it's a noisy minority at both ends of the spectrum who are stirring things up.

Indeed, reminds me of how I was mistreated when i first came to the wiki. Things certainly havn't gotten much better since then...
