Which is essentually saying it's all bullshit... because you know that's what stories of the WMDs in Iraq were.... bullshit.
No, once again, he's saying that the atmosphere of smearing anyone who questions the anti-Russia stories (that end up being debunked over and over again) as a Putin stooge or Russia apologist is similar to the run up to the Iraq War, where people who demanded evidence for WMDs in Iraq were attacked as unpatriotic Saddam apologists.
Why is it so offensive for a journalist to say that other journalists should have higher standards? No one can deny that the Russia hysteria has been overblown and, to this day, there is still no proof that Russia impacted the election in any way. Once there is verifiable proof, then by all means publish the story.
