Henning's 82nd maxim for Staying Sane on the Internet

Against random individual opponents I will defend the reasonableness of my opinions, but not my moral right to hold and express them. If the latter cannot be assumed granted, then why are we having a conversation in the first place?

(I will, however, occasionally defend the right of others to hold and express their opinions, when it needs doing and does not appear to be too pointless. That's different.)
