As a past and future speaker of LambdaConf, I wanted to share my thoughts on the Curtis Yarvin controversy.   I do not agree
with excluding attendees nor speakers because of their beliefs or writings.  However, it has become clear to me that Curtis Yarvin
has been and continues to be disingenuous when it comes to his claim of separating himself from his 'Moldbug' persona.  This, combined 
with his large sphere of influence in a repgunant political movement leads me to believe having Curtis at LambdaConf will detract from
the overall goal of spreading functional programming as well as reaching under represented groups.  I do not support Lambda Conf's 
decision to allow Curtis Yarvin to speak in 2016.  I coninue to support LambdaConf's overall mission of inclusion, am happy to see they
continue to offer divirsity scholarships, and plan on speaking in 2016 despite Curtis Yarvin's attendance.
