I think the request is fair. Be time-idempotent; imagine if you were talking to someone from the 15th century and they were SURE they were right about their crazy opinions. The meta-stable way to be reasonable is that as long as someone seems to be honestly asking the reasoning for your beliefs, and your principles, you should try to explain yourself, rather than just shut them down by repeating your assertion of correctness. Otherwise, how will you find out about the likely beliefs you hold right now, which our descendants will consider insane and evil? Forcing yourself to self-introspection is a good practice. I don't expect anyone to change their mind about this, but being able to explain to others your reasoning can also clear up your own views, and help convince your adversary much more effectively than the "just repeat your position" argument style.
