They chose that name for themselves because “Communist Party USA” was already taken, and “Lying spawn of Satan” didn't focus group well.
On the website for “Catholics United,” there is a set of links to Facebook pages of supporters.
“Christina” is a supporter of two different state chapters of NARAL, the pro-abortion lobby. “James” advocates revocation of tax-exempt status for churches who take a stand on controversial public issues, even though other “friends” are writing the bishops to support ObamaCare. “Jason” supports same-sex marriage throughout the United States. Although they claim 933 Facebook “friends,” “Catholics United” only lists ten, so that is as far as my survey can go.
