My thought exactly.

Let's see. Guy threatens GA. Guy is safely on the plane and physically away from the GA. GA then decides that the thing to do, for her safety is to pull the already agitated guy off the plane and bring him back to where she is at.

When I feel physically threatened by someone the last things I want to do are to 1) piss them off even more; and 2) move them closer to me.

Also, for those saying that this is not a free speech issue, consider that the GA used her power (which is granted by the government) to intimidate a US citizen for the content of his speech. She threatened to have him arrested. That was a credible threat because the US government has granted broad powers to airline employees when dealing with customers. This situation did involve the threat of government action.
