So here’s what I would say to this:
If they are not sins, why confess them? If they are not sins, why would one think that they are? To me it would indicate knowing on some level that they might be, even if it was just a small matter of disobedience, which, of course, isn’t necessarily a small matter at all.
If they are sins, and you do confess them, are you prepared to change? We must go to confession with firm purpose of amendment. So if we confess, and we do not intend at least on some level to stop sinning, or at least consider how we might, then there’s no point to it.
You aren’t doing these things, so obviously you’re not sinning by doing them. And you say you’re not advising anyone to do them, so you’re obviously not sinning in that way either. From my chair, if you came into my office and wanted to discuss this with me, my concern would be less “is this a sin?” and more “why is it you believe this, or why disagree with the Church on this?” I would give a hearing to your arguments and I would discuss it with you. If I convinced you, great, if not, I realize that happens sometimes. It would be better if you didn’t believe those things, but I recognize that I can only do so much, and the rest is up to you and the Holy Spirit.
If you would like to have that conversation, feel free to PM me. I’d rather not adjudicate it here, lest we get off topic or invite any nastiness directed at you. I don’t mind intellectual discussion, I can’t abide nastiness.
