they also support Unitarians, Jehovah's Witnesses etc. over Catholics. Next you can expect such people would also support Obama liberals etc. as long as they attack Catholicism...
A vibrant and faithful Church is a continuing testimony to the errors of Protestantism. All one need do is to see that the target of their attacks is not secular socialism, radical feminism, the abortion industry or even militant Islam, to understand their motivations are not in line with promoting the Gospel, but in advancing their own self esteem. Pray for them.
Peace be with you
