> Not believing the Snowden leaks is akin to denying the Holocaust IMO.

The parent's wording may have been off. My parsing of "He also doesn't believe the Snowden leaks" inferred a missing "were justified".

Then again, I could see a few different interpretations. We need a clarifying phrase after "doesn't believe the Snowden leaks", like "doesn't believe the Snowden leaks were justified" or "doesn't believe the Snowden leaks tell the whole story". One parsing is "doesn't believe the Snowden leaks are legitimate and authentic".
