First off, you should never have to apologize for something you say. You should always say what you mean and mean what you say.
You should always measure your words before speaking them ... especially if you are on TV or radio.
Remember Rush calling poor little Sandra Fluke a Slut? Oh my, the Liberals were unhinged, and that was just a thought spoken aloud.
I will say this, of all the recent Liberal (non-apologies) Apologies, Bashir’s seemed sincere and didn't rely on any word tricks. Whether he believed what he was saying I do not know. That's between him and his Conscience.
