While certainly wild, the reason I don't give these allegations any credibility is that not one shred of proof has been provided to indicate any part of them are true.  This document has been circulating for six months and the intelligence agencies (for all there good and bad) and news organizations (primarily for their bad) have not been able to substantiate anything in this dossier.  (Which by the way is really fun reading.)  If there was the least bit of anything being truthful it would have been reported.  For example the supposed meetings in Europe by the Trump attorney.  The FBI looked and can't find him ever having gone there and even the attorney said he had never been there.

So, allegations they remain until something actually is proven.
