Your perception of theists

[Pyrrho]

So... are you compiling all this data into some database to be used for Xtian world domination or something? You certainly have a lot of info from all of us. I'm skeptical about where all that is going, and what it's used for 

No, no conspiracy theories up my sleeves... yet. ;-)

Haha, I'm actually just curious, really. I like knowing the thoughts of people who have views that are so different from my own, and I believe everyone has something to offer and is someone I can learn from. It's nice to be able to openly talk with all of you here. The atheists I'm friends with in real life don't feel very comfortable talking about this sort of thing with a devout Catholic like myself, which I think is unfortunate.

There are likely several different reasons for this.  For one thing, there is the whole history of the Catholic church, with the Inquisition and so forth, that really does not make one wish to open up to a Catholic about things that Catholics have tortured and murdered people over.  And then there are the modern assholes one encounters, and one may wish to not deal with their assholishness that will be the fallout from discussing such things with them.  And another thing (and this might be most applicable in your case) is that many people get upset and don't want to socialize with people with whom they disagree, so it might be that some of the atheists with whom you are acquainted like you and don't want to upset you and lose your friendship.  Or it could be a combination of these things, or an uncertainty about these things in connection with you (which will particularly apply the less well the person knows you).  And there might be some other reasons that do not presently spring to mind.

Here, most of us are anonymous, and so people can feel free to say things that they would not normally say.  Of course, some people are habitual liars, and anonymity does not change one's fundamental personality.  And in the case of self-reporting, people are notoriously unreliable.  That is, people do not know themselves as well as they often believe they do, which is well-established in psychology.

As for your question in the OP, believing in superstitious nonsense is going to affect the way one perceives a person.  The person might otherwise be intelligent, nice, or whatever, but it is not a good thing to believe unsupported things.  That is, it is not a good thing to have faith, to believe things in the absence of evidence, as that is prejudging things before the facts are known, which is prejudice.  Prejudice is a vice, and since there is no good reason to believe in a god, we know one bad thing about the person if we know the person is a theist.  Of course, that is only one thing, and the person might be, overall, good, but it is still a bad thing that we know about the person.  If you know only one thing about a person, and it is bad, it naturally makes you think less of them than if you did not know anything bad about the person.

For more on the idea that faith is a vice, see William Kingdon Clifford's essay "The Ethics of Belief."  You can read it here:

You can also read a response to such ideas at that same site, and a response to the response.  If you want, we can start a new thread to discuss Clifford's essay.  You can either start it yourself, or ask me to do it (if I do not seem to notice your request, you can send me a PM asking me to start such a thread).
