Apologies, I was trying to get a better understanding of the MMX without the notion of an ether wind.
Apologies, I thought they were different questions
In the scenario of the moving train, where the slower relative [to the train carriage] speed of light would be offset by the slower ticking light clock, would the use of such a mechanical clock to measure the speed of light lead to the observer measuring a slower speed.
I don't think it's a matter of arrogance, rather a matter of reason.
The objection to Lorentzian relativity, that usually seems to get cited as the reason for preferring Einsteinian relativity, is the fact that it doesn't have the undetectable, absolute rest frame; while Einsteinian relativity appears to treat each reference frames as though they are that absolute rest frame - that doesn't appear to be too different from my own reasoning.
However, that I find it more objectionable is not necessarily a conscientious preference for one over the other, rather that from trying to develop an understanding of both theories, the process of assimiltation of information has lead, for some reason, to Einsteinian relativity not sitting well; that could be, in part, due to the reasons that are given for preferring Einsteinian relativity over Lorentzian.
EDIT: also possibly because it seems like the superfluous assumption [of an absolute rest frame] that seems to make Lorentzian relativity less attractive, could probably be done away with, within the context of Lorentzian relativity.
