You are 100% correct that my comment did not show any bias at Twitter, as I referred to something that did not occur.

Instead I appealed to the reader's intuition about a counterfactual, showing that the reader already knows and has internalized this balance at the moment, by appealing to the reader's intuition at how surprised the reader would be: not at all surprised to read "Twitter has banned Donald Trump" - though this is a counterfactual - and on reading that headline would know that a liberal employee would have done it.

Do you consider the hypothetical headline I just quoted highly improbable? (I don't.)

Not saying this status quo is good or bad - I was just answering the question.

EDIT:

So I'm walking with someone, and he said that he couldn't see it happening. The reasons that he gave were that it would be very bad for business because a lot of Republicans also use Twitter and that since it is the president of the United States, he could argue that this is a public function. So would be limiting his freedom of speech in a sense.

So I guess I'm wrong and it would surprise many people.
