this is a public event (second entry in column on the right):

Hosted by the Office of School-Family Partnership officially "School Family Partnership," formerly Family Engagement is an official committee of Portland Public Schools to enhance parent engagement listed in the S section:

At Blanchard Education Service Center, 501 North Dixon Street, a public building owned by Multnomah County:

If you are a constitutional statist then any first amendment prohibition at a public event hosted by a government entity on public property organized by public servants ought to generate suit. You do not sue the School Family Partership or the Portland Schools unless an unreasonable first amendment prohibition is a matter of policy. Sue all 16 of those officials allegedly present from the office of School Family Partnership individually and personally in federal court for any abuses of discretion. Ignorance of the law is not an excuse. Some of these public servants should be taught a lesson in what the law is by getting their asses hauled into a federal court.
