I think I should rephrase my stement a little (revision in bold)...
Nor is there any overarching effort to censor a wide-ranging debate on Illegals, as far as Ive seen. In the context of the current effort underway on the Illegal Alien threads, I havent received even the slightest hint that there are subjects that are off limits to me in this regard, nor have I been given the impression that there cant be vigorous debate, and Im hardly a party-liner in this.
I'm aware of a few sites that aren't allowed. When I've gone to those sites from time to time, I've mainly seen articles that would be acceptable at FR, but for the fact that they're from forbidden sites.
If there are other aspects of those sites that make them entirely objectionable, I haven't seen much in the way of a thorough explanation of them, though I've asked.
It's a discussion worth pursuing, in my opinion.
