While I agree that Reddit is awash in (multiple) state propaganda, and that posting violent rhetoric, or even sympathy for it, there is likely to put you on a list (or multiple), I don't think Reddit users really trust it's that safe. In the last year and a half, since Luigi, there has been huge amounts of bitterness over the censorship of content and strict banning policies. People have discussed, and followed through on, leaving in droves. Huge amounts of old content are no longer available because people scrubbed their post history on the way out.

If the current discourse doesn't reflect that, I would suggest it's because :

1. the real people still there remain to discuss uncontroversial niche topics
2. political discussion there is largely driven by bots and paid actors now
