Peace, man. Absolutely, whatever you're comfortable doing. Wouldn't dream of lecturing you! I was just trying to understand how using cloth masks might make sense here, since it wasn't, and isn't, clear to me. I don't mean that, not for a minute, as an exhortatation for you to stop doing that!

As far as the car thing, well, clearly you were going for that literally. The analogy I was going for was --- well I guess I'd best spell it out now --- if one's doing the deed, and thinks protection is called for, well then one uses protection that's fully effective. If some protection is available that is more effective than zero protection, but still much less effective than using the regular protection, well then I don't see why one would go for the less effective protection. If one decides --- rightly or wrongly --- that one doesn't need protection, then one goes without. But if one decides on does need protection, then I simply don't see the logic of using the less effective protection.
I'd imagined that you were, half-jokingly, referring to the same analogy as mine (of doing the deed), except using a further analogy of cars rather than directly alluding to it. Jokingly, of course, because after all there's no kids here, and there's no reason why we shouldn't directly speak of sex and condoms!
But like I was saying, it's just that I wasn't getting where you were coming from, as far as that, and wanted to see what it is I'm missing. Don't mean to lecture you or anything. By all means, whatever works for you!
