1. I am not trying to separate faith and politics, but that has nothing to do with priest's trying to judge who is standing in front of them. 


2. Politicians, Catholic or otherwise, do need to provide information on their positions on issues for voters to make decisions. Your continual point that they are "supporting abortion" is, of course,  only YOUR interpretation of what they are doing; I'm guessing that they are actually doing something else that you don't accept as it is, but prefer to interpret as "supporting."


3. And, finally, it's "its" not "it's" in your third paragraph, first sentence. A common-enough error, but it does distract the reader from the content.
