Is that exactly what I say isn't wrong? Let's see:
That's why you are being worked up and calling me a liar? First of all, that's a rather scandalous aproach to a discussion. I'm not sure how badly Christians have been pestering you and hurting you in the past, I don't think there's a need for it to project that on me.
You've asked a question, and I'm trying to answer it. In the very least try to give me the common courtesy of assuming that I'm not trying to maliciously deceive you and lie to you just so that I can prove to you something that is inconsequential for me personally, since I have no idea who you are.
With that in mind, let's review to put some background to my "lying" statement, especially since you seem to be confused what my point is, and I've made it several times:
1) Morality makes no sense for a lone person marooned on Mars all alone with no chance of anyone ever getting there to keep him company. Secular layer of human morality is a social construct as it relates to certain social needs and necessities that we have as people.
2) I've painted you a whole score of scenarios in which doing something alone doesn't automatically translate into it being moral, because, as you've conceeded, nothing (or perhaps not much) is truly without any potentialities if it exists in some social setting, even if temporarily isolated.
3) In which case, all I can convince you is that swearing in public is problematic, and if it is indeed problematic in public, then it's problematic in private because of similar potentialities. Just like with cheating on a test or cheating on one's spouse in private is not without certain negative consequences, even if these are not divorce or failure.
Now, on to your lying accusations:
You've made below statements where you seem to indicate both, that you don't see swearing as bad in either case.
No, it's not. I swear casually all the time. Sometimes I swear at people when I'm angry. You could call that wrath, but not all the time. So no, it isn't any more wrathful than "shucks" or "darn" or "shoot" or "golly".
So, unless I misunderstood you in the above, the context of swearing that you've painted included both "occasional public" and private use of swearing that you've seem to defend. Hence, my statement about "doing exactly what you do", wasn't directed at some vacuous context that you didn't bring up.
So, unless you don't swear, or never swore in public, I see no point to your objections at all, especially calling me a liar.
All I did was to point out a generic attitude of people who do acknowledge that they shouldn't devalue sacred concepts of other in front of them.
I then take it further and say that it may not be a good idea to do that "not in front of them" either, because we are habitual beings, and what we consistently do in private can turn into habits that will reflect on us in public.
So, please show me why and how I was lying again in saying any of the above, especially when you say something as ambiguous as below:
Secondly, the burden is on you because you're making the positive claim, and I would be making the negative claim. You want to prove there is some reason that cursing is bad, I would be proving there is no reason that cursing is bad.
Do you or do you not think that public use of "G/D" is immoral? I can't actually demonstrate it to you until it's immoral in private, UNLESS you can concede that it's immoral in public.
