I will defend anyone who wants to speak and discuss things openly, but I will do so according to my principles, not theirs, and there is no hypocrisy in doing so. If you would defend a Christian's or Muslim's right to their beliefs without giving away all your possessions or travelling to Mecca then you are in the same boat. The values I would hold in a perfect world can be impediments in this one, especially when they are used to push orthogonal values.
More importantly though, I like Scott, but I think he is preposterously naive and friendly to a fault. And I think that has been weaponised against him countless times in the past, and is being weaponised against him now. And nothing makes me angrier than seeing friendly, charitable people being taken down by the vindictive and unscrupulous.
It would feel, to me, inappropriate to do otherwise while defending him.
