A Republican lawmaker from Keizer is encouraging gun rights supporters to personally contact three Portland clergy leading an initiative campaign to ban assault weapons and high capacity magazines in Oregon.“Should anyone want to make a phone call or send a note….” Rep. Bill Post wrote on Facebook Wednesday morning, above a photo of the phone numbers and home addresses of the three chief petitioners for the initiative displayed in a state database. “Feel free to right click and save the picture then share everywhere.”Post, who described the initiative as a “gun confiscation ballot measure,” declined to say why he felt it necessary to post the information to a Facebook group called The Heirs of Patrick Henry, Northwest. “Knowledge is power,” Post said in a phone call Thursday afternoon. He said he had called the petitioners and left voicemails about the initiative, but declined to share his message, saying it was “between me and them.”One of the petitioners, Rabbi Michael Cahana of Congregation Beth Israel, said he was wondering why he received “quite a number of calls on my cell phone.” The people he spoke with were mostly polite and “certainly shared their views” on the firearms proposal, Cahana said. Comments that arrived via email and Facebook were “not so polite.”Cahana and the two other petitioners, Rev. Alcena Boozer of St. Philip the Deacon Episcopal Church and Pastor W. J. Mark Knutson of Augustana Lutheran Church, filed the initiative this week and must collect more than 88,000 signatures by July 6 to get it on the ballot for the November election.
