Mmm; that's fair. The husband had an XPS 13 (not sure if that old, though; it was the one where you could get the cover in Rose Gold) but they only use Windows so I can't say. I've mostly installed Linux (for myself) on Latitudes.
Oh, for sure; it is definitely impressive. I dunno if you already know (so, basically, I apologize if so!) but part of how Apple's able to pull that off is they manufacturer their own hardware and only install to it; so OS X's optimized to the hardware in a way Windows and Linux can't be (since they're designed to run on any hardware). I'm sure that's not all of it but it's part of it.
Oh; I think I've miscommunicated. I'm sorry about that. I wasn't saying that they don't go to Heaven; I mean, – technically – one could believe that, if one wanted (there have been no dogmatic statements that that isn't what happens; in the middle ages, there was this theory than unbaptized infants went to a place called Limbo which was neither Heaven, nor Hell, nor Purgatory. It never really caught on as I think most people find something unsettling about a baby, of all things, not getting into Heaven. So one could believe that but most writing on the subject has assumed the non-believer can go to Heaven).
Of course, this whole thing necessitates that you believe in God and that God is Good (since that's the perspective Catholics are writing from) but, if we assume these things are true about our world, one could not believe in God while not realizing morality and the Good of the world stems from Him. This becomes a mortal sin when you realize that these things stem from God and then still choose not to believe and reject him. Because – if you truly understand He's the source, etc. – to still say, "I still won't follow Him," kind of requires that you…don't do the things that are Good either, right? So, when we say that non-belief is a sin, it's a little different than your average, say, Evangelical for whom the belief is the point, full-stop. Hopefully, I'm making more sense and not just being verbose…
It's a fair question; I'm pretty certain it's a common fallacy (might not be the most accurate word…) that those who argue against religion – or Christianity, specifically – point to.
I think the issue is you're considering these things non-harmful; in Catholic theology, sin separates us from God (to say the common quote) which hurts us but, to phrase the same thing differently, – since He's the embodiment of morality – means we act immorally and hurt ourselves and others. So these things are things which are inherently hurtful and doing them would cause harm, regardless of belief or not. In theory, part of worshipping God is choosing the best thing for you and that's part of the point in converting people (again, we're not really the by-faith-alone people).
But I think you'd counter that these things aren't really harmful (or, if they are, it's certainly not evident outside of the Catholic Church telling you so). And that's where I reveal that…I'm not an entirely orthodox Catholic and it's not your logic that's being wonky.
Outside of the eating-meat-on-Fridays (as that's more of a practice of worship and I don't think that grievous to perform, if you're truly on board with the whole belief thing), I do find these positions…misguided. I don't know whether there's any way to reconcile them during the development of doctrine or they never will be. Maybe I'm the one who's wrong; obviously, people have fought over these topics for many years.
But, in short, I think the reason your premise makes sense is that it seems more like extra chores than anything else but I think it makes more sense if you bear in mind that most Catholic theologians believe these things truly are harmful not only to our souls but also our bodies (brains included in that; not trying to draw a distinction).
