I like Father Z and usually agree with what he has to say, but I think I have to disagree a little bit with him, and a little with you as well, on the standing/kneeling part. (I do actually prefer to receive from the priest and do so when I can without being disruptive, but do not mind receiving from someone else when required.)
“The norm for reception of holy Communion in the dioceses of the United States is standing.” The argument I’m reading here (correct me if I’m oversimplifying) is that the document is simply saying what is happening rather than what should happen.
The word “norm” might imply that the the statement is not always applicable, but the fact that they bothered to mention the issue hints that it’s more than a mere observation on what is going on. It seems to me that officially writing it as a norm is defining the method the Eucharist should be received, but possibly with some exceptions. It does not seem like just mentioning what usually happens would be worth the time I’m sure went into the document.
I can see the exceptions to the norm including the extraordinary form of the Mass and ministering to those who cannot leave the pew. I cannot see the exceptions including personal preference, even if motivated by the deepest respect for the Eucharist (as such a preference would almost certainly have to be by its nature). If so, then why mention the norm at all? I can see attending the Extraordinary Form out of dislike of the Ordinary norms, but I cannot see using respect for the Eucharist to justify participating in the Ordinary Form in a way contrary to its design.
“Communicants should not be denied holy Communion because they kneel. Rather, such instances should be addressed pastorally, by providing the faithful with proper catechesis on the reasons for this norm (GIRM 160).”
As the apologist Michelle Arnold pointed out (
forums.catholic-questions.org/showthread.php?t=488083) this seems to suggest that a person who kneels should be corrected. It says, basically, “if they kneel, give them the Eucharist but tell them not to do it again later.” Which means that you really shouldn’t be kneeling in the ordinary form.
To call kneeling at communion “disobedience” probably would depend on whether or not you have been instructed not to. If you’ve been convinced that the norms say not to (or even if you haven’t but the local Bishop or presiding priest told you not to), then yes it is.
As a last note, Father Z seems to hint, I think in an (at least partially) joking manner, that standing for the Eucharist is a product of a misguided modern attempt to replace the idea of the Awesome God - whose power is such that even his mere messengers have to introduce themselves with “be not afraid” because the infinitesimal portion of God’s power and glory that manifests itself in them could easily terrify the people they’ve come to see into some sort of trembling catatonic state - with Buddy Jesus.
There might be something to that, I don’t know. I’m young enough that while I find the Latin Mass beautiful (except the one time the two altar servers were silently bickering behind the priest’s back - not even the Latin Mass solves all such problems), I am more comfortable in an English version so long as it doesn’t have tambourines. I wasn’t around for the transition. I do understand that someone used to the Latin Mass might be uncomfortable with most Ordinary Form Masses, though I have been to (and prefer) tambourine-less English Masses that are just as solemn and beautiful as the Latin Masses I have attended.
So I can see why a person wouldn’t want to stand to receive the Eucharist out of respect, and I can see a preference for the Latin Mass (they rarely have tambourines, as I understand), and I imagine that the only reason why I don’t share these sentiments is that I grew up seeing the Eucharist received standing in the Ordinary form. But despite a understandable preference for the Extraordinary Form, the Ordinary Form of the Mass is still a Mass, and the norms that determine its celebration require as much respect and adherence as the norms of the Latin Mass do/did during its celebration, when it was the ordinary from and now. And these norms are the norms even if we don’t like them. If our respect for the Eucharist forces one of us to refrain from receiving standing, then it may be that the only solution is to not receive at Ordinary Form Masses. It could be that I’m being overly picky here, but I cannot make myself reconcile ignoring a norm of the Mass for a personal devotion, no matter how well meaning. (After all, all the liturgical abuses, such as tambourines, that we witness at Ordinary Form Masses all the time are also well meaning. The problem with these is that the personal ideas of what is good intrudes upon the Mass in an inappropriate manner, not that the person who commits them doesn’t have his heart in the right place.)
In conclusion, I really hate tambourines.
Couldn’t help but reply after re-reading your post…Your fellow-parishioner is concerned that you only want to receive from the priest?. 
Gives me chills. If that were a conservative Catholic speaking, we might be accused of paying too much attention to other worshippers instead of our own prayer, etc. While we have to agree with Holy Mother the Church’s decrees - and while there have become needs at times for ordinary ministers, I’d think Church attendance is so in decline in numbers that there almost wouldn’t be a need. I say do as your conscience tells you - particularly, in cases of your Faith and Tradition. Don’t worry or let others give you pause. God love you.
