::Well, certain users, including  have suggested (at least to my understanding) that while wtc7.net should be excluded as an external link (for reasons I strongly disagree with), it should be possible to insert links to other sites expressing the controlled demolition POV in order to bring the article into concert with WP:EL.  I believe there are very few users who are arguing that the controlled demolition POV is not notable and therefore should not have any external links dedicated to it at all.
