How to handle tax protesters in an ethical manner

Michael Hatfield (Professor of Law and Associate Dean of Research and Faculty Development, Texas Tech University School of Law) has recently posted on SSRN his essay entitled Tax Lawyers, Tax Defiance, and the Ethics of Casual Conversation.

Here is the abstract of his essay: 

This Essay addresses the increasingly common social situation in which tax lawyers are confronted with tax protester arguments and similar anti-tax system comments. This Essay seeks to place these conversations in a greater context of tax policy and ethical considerations, urging tax lawyers not to walk away from the conversations but rather to engage with hopes of educating the public, improving the law, and protecting the interests of the vast majority of Americans who pay their share of the price of civilization and expect others to do the same.
