The main reason this logical doesn’t work is, that the difference is as follows: there are plenty of new rite masses all over the place, so you and anyone who would think of doing this would have no reason to attend the old rite if you have no interest in such centuries of beautiful inspiration inspired by the Holy Spirit. On the contrary, there are very few old rite masses available, and so some, like me and the writer of the post have to attend the new rite sometimes in order to be at Calvary, unless we travel miles, and so we have to make the most of what we can get, and normally in churches which originally had the traditional mass and now suddenly no longer do.
Also, regardless of who is right, to kneel or even to sit is a discreet act, but to stand up while everyone is sitting is to clearly and deliberately stick out, but that’s fine, be my guest. I have no guilt in being the only one kneeling, but if I was the only one standing, it’s not so much just guilt but I’d feel very embarrassed. Although to be honest, hopefully I would not notice if someone was standing because I hope that I would be occupied by prayer and focusing on the lord at that moment.
