Yes, I can imagine there are lots of instances where an honest, but less mature, person might not be sure if he was sinning. Therefore, it "might" actually be possible that for the exact same act, it might be a mortal sin for one, but not for the other. I usually use John Kerry as my official whipping boy on the issue we are talking about, so I doubt he is unaware of the official Catholic position on abortion. :)
Condemn wrongful acts, certainly, but I've always found it more salutary to worry about my own spiritual state than to draw conclusions about that of others -- my own opinion, anyway!
Fair enough. But when it comes to liberals, sometimes I just can't help myself. I hope that's not a sin! :)
Hey, I'm from MA -- you can't be any more appalled by Kerry than I am! Of course, he's clearly delusional (actually, I really think he is!).
Rail about his behavior all you want! :)
