That's true to an extent. It's more about avoiding arguments, though, and less about whether the view is orthodox.
For example, some views are so out there and unaligned that people will just think it's a joke and not fault you unless you start seriously arguing for it, like if you say murder should be legal.
On the other hand, some orthodox views would still get restricted because they're contentious. Like if you start talking about how you believe in equal rights, that's something most people agree with (at least in principle,) and it shouldn't be political. But it's going to ruffle some feathers anyways (especially if you get any more specific than that,) so it'd be restricted.
So basically, it either has to be so out there that people won't think you're serious, or so commonplace that people won't even consider that it could result in arguments.
