I agree with Decius. Do you have a wiki account, so you can post your own edit under your own name?
I don’t have a wiki account, and I don’t feel the need to retain credit.
I might clean it up a bit if I was putting it out for summary rather than for discussion:

I’m not sure if using this line to convince others that lies are immoral is hypocrisy, meta-hypocrisy, or both. The statement itself is purely rationalist pragmatism.
