I support NSN’s policy of engaged neutrality as written. It is especially important in times of widely varying opinions and sociopolitical divisiveness to provide a forum where all sides of an issue can be examined. In my experience, to act otherwise is to essentially become a political action committee in the eyes of the government. NSN could maintain a federal non-profit status, but donations to the organization would no longer qualify for tax benefits as charitable deductions. Someone with more recent and deeper legal knowledge should look into this aspect of the law.
Whether to hold the conference in a “heartbeat law” state is a separate issue, but to change venues now, after a location has been announced, may put our current legal status at risk.
