I think I've made pretty explicit claims about political moderation by Instagram. Personally, I'm not a huge fan of racism/sexism/etc. so I find it hard to mind, but as I've shown, they also moderate contested political claims, like stuff about Biden's crime bill, Hunter Biden, etc.

Those are political issues, and I've provided evidence of them enforcing that viewpoint. The original comment provided no actual evidence of Parler enforcing a single viewpoint, but we all know what Parler is so it doesn't take (me at least) much convincing.

I've explained both why my comparisons are not logically flawed (no evidence that Parler pays for a "certain political agenda") and have stronger epistemic backing than the claims being made about Parler.
