@Lash,
Lash: As maporsche stated, the Steele dossier is an investigative report. Steele was hired by a firm working for the conservative Washington Beacon website to do opposition research against Trump. This was when the Washington Beacon website was against nominating Trump. The report was meant to report information, not prove anything.
When the Beacon switched sides and supported Trump, the firm gave the dossier to the FBI. The FBI examined the report, and found that there was nothing in there they were able to check out one way or another which was false. Therefore, the Steele dossier quite rightly is considered reliable information.
The fact that you received a pat on the head from Finn, who plainly has no ammunition to show the report is not reliable, means nothing. Both you and Finn have been wrong about this report all along, and have been trying to tap-dance around that fact for over a year.
