I don’t know if you want this feedback, but this wording reads to me as passive-aggressive. It’s a cumbersome wording (“seems odd to me”) and an indirect (passive) way to criticize an error (aggressive).
A more direct version, just as an example for comparison, would be: You say you don’t understand this, so it doesn’t make sense to comment on it, particularly with a strong opinion. Commenting is implicitly premised on understanding the thing you’re commenting on. A better way to deal with not understanding something is to ask questions about it.
Another reason I thought it could be passive-aggressive is that I saw a trigger for that type of response. The trigger was the arrogant, aggressive, non-tentative comment that you were replying to:
Deutsch is just dead wrong about this.
And that was actually part of a pattern. Earlier in this thread, lmf was similarly dismissive of DD’s ideas about physics, in favor of his own:
but that’s simply false.
If you were offended by these comments, or disliked or disagreed with them, there are better ways to handle them, like commenting directly on what you think is objectionable about them.
If there was some other cause in this particular case rather than being passive-aggressive, then your text miscommunicates, which is also bad. One enabler of this kind of miscommunication is being capable of being passive-aggressive, rather than having automatized awareness of the issue and its problems – that enables writing stuff that sounds passive-aggressive, with the wording intuitively seeming normal instead of you noticing the problem, even when actually something else is going on.
A difficulty with this kind of writing (both the passive-aggressive sentence and the arrogant sentences) is people often intuitively know what it means but don’t explicitly, consciously know what they are reacting to and why. People often get impressions, emotions and intuitions, based on their subconscious and automatized knowledge, without knowing exactly what happened. That makes it hard for them to address the issues directly or specifically. That’s one of the things that happens to me: People feel like I’ve been mean to them, and then when I ask for a quote with an explanation of what was mean about it, they can’t give one. But they still have the feeling and general negative impression. They often fail to problem solve that themselves and also don’t ask for help with that problem solving process (they often also reject help if I offer it, claiming that the problem is solved as a way to end the discussion. They say this when they have not automatized better knowledge; they just reached a conscious conclusion that they were wrong and then tried to suppress their feelings that they regard as irrational and perhaps also static memes). This kind of thing causes a lot of trouble and is one of the ways people end up failing.
BTW, I am interested to see some continuation/resolution to the debate about string theory. There appears to be a substantial disagreement between two people who both have some relevant expertise.
