Are Christians being silenced?

The question sounds like the perennial complaint from members of the Christian Right. But in fact, as specious as the Christian Right's complaints along these lines usually are, this one is different. Not only does the complaint originate elsewhere -- but the Christian Right is the beneficiary of the apparent silencing of fellow Christians.  

When the Sunday morning public affairs talk shows think about getting a Christian view on public affairs who do they call? According to Rev. Robert Chase, Director of Communications for the 1.3 million member United Church of Christ, over the past 8 years the Sunday network public affairs shows have interviewed political leaders of the religious right 36 times, and leaders of mainline Christian denominations such as the United Church of Christ, United Methodist Church, Presbyterian Church (U.S.A), American Baptist Church, Evangelical Lutheran Church in America, African Methodist Episcopal Church, Christian Church (Disciples of Christ) and African Methodist Episcopal Zion Church, Reformed Church in America, the Greek Orthodox Archdiocese of America, among others -- exactly zero times.
