As a secular humanist myself, my big problem with the (H)umanists is that they use their worldview as a cover for the promotion of socialism.
I concur with your critique, they are thick as fleas in Pugetopolis as you found out. For the past 12 years or so, in Kitsap County more than 3/4th’s of the elected RAT politicians from school board member up to commissioner are secular humanists and they too meet at the Unitarian Universalist Center in Bremerton. What a coincidence?!?!?!
