Dissent is allowed. Anyone reading the posts on the various threads will see that.
What is not allowed is disrespect. If one is to discuss the theology of a Church they do not belong to they may do so, and they obviously do this regularly. A Catholic might say that he rejects Orthodox teaching on Topic A. An Orthodox might say that he rejects Catholic teaching on Topic B. What one may not do is to say that the theology of someone else's Church is stupid, etc.
I remind all posters that when they twist facts, are disrespectful of other posters, or in other ways exhibit a lack of Christian brotherhood they make fools of themselves. If you need to do such things the argument you are presenting will never win.
Regarding Weigel's article (the one under discussion in this thread), I find much in it that is accurate.
There is a deep historical pessimism in Ukraine, born of both a colonial past (which taught Ukrainians that they were an inferior subspecies of the eastern Slavs) and a totalitarian past (in which millions of Ukrainians were deliberately starved to death as a matter of Soviet state policy in what seems to be the forgotten horror among the 20th-century genocides).
I think, however, the issue is far deeper than that, goes back much further, and has a lot to do why even today Greek Catholics consider themselves to be second class (even in America). But that is a separate discussion that we've had before.
The link that DMD provided to comments by Bishop Demetrios provides (IMHO) a good filter in which one can read Weigel. George Weigel is obviously a very good man with the best of intentions. But he has no understanding of the Christian East. If he did he would follow the example of Pope John Paul the Great in treating Orthodoxy as if the "only thing needed for communion is communion".
