Now would be a good time to describe what specific issues you have with Greenwald's reporting on past issues and where he's been inconsistent with facts revealed after the fact.

His stint at The Guardian where he broke the Snowden leaks?

His work at The Intercept that revealed the corrupt dealings that led to Brazil's Lula losing the election and being imprisoned?

Or is it his appearances on US media, where he's on record for questioning the efficacy of Russian interference in the 2016 election (which IIRC is backed by a study in Nature Communications) and criticizing Israeli influence in US politics?

I'm not disagreeing with you, but you're not exactly providing much in the way of evidence outside of your own opinion.
