Judge Not Redux

Great post on Fr. Z's site referencing His Hermeneuticalness on a post which is pertinent especially to us bloggers.  This snippet mentions politicians, but the idea applies equally to our ecclesiastical leaders:

Judge not, that you may not be judged. For with what judgment you judge, you shall be judged: and with what measure you mete, it shall be measured to you again. (Matt 7.1-2)

How often do we see this verse quoted in response to Catholic blog posts? Criticise the public actions of a politician or a high-ranking ecclesiastic and you can be sure that someone will say that you should not be "judgmental". Should bloggers cringe in shame at failing to observe the teaching of Our Lord in the Sermon on the Mount? I think we can reasonably take a deeper look at this.
