Sure, but the equivalent would be to host your content on a Raspberry Pi that is not connected to the internet. What would be the point ?
Even hosting via Tor can have consequences, if the government has enough incentive.
However, practically speaking, I think the OP would probably be fine posting on AWS, as others have remarked.
Because you're not free if you can't do that.

Then you can chain Tor with other anonymity networks. Such as nested VPN chains, Orchid, or LokiNet.
Based on what I've seen, people have generally been pwned because they screwed up, and not through fundamental compromises.
