"The present" is not meaningless.
It is in the context of the logic of making a choice. Either it is (in a strcit sense) a single, infinitesimal instant, in which nothing can happen, or (more colloquially) it is a short amount of time during which several things can happen in the normal sequence and subject to the logic I presented. In neither case does it affect the logic. In the former case, nothing can happen in the present, so your statement about it is nonsensical, and in the latter, it is irrelevant.
Again - this is something I've explained before and you just ignore it.
It is simply defined by where our conscious awareness exists.
Which firstly, doesn't change what I said above, and secondly, makes your whole statement about "conscious awareness" that "exists and acts in the present" into a pointless, and entirely meaningless truism.
I am sure the vast majority of people on this planet would agree that this is a logical definition of the present.
Only those who don't understand logic. It's a vague and imprecise definition that has zero impact on the logic of how minds work.
It is not in the past, it is not in the future, it is where I exist now.
Except that you don't in any strict, logical sense. Composing that message in your mind and then typing it out happened over a period of time. By the time you'd finished, the start was in the past. And that's before we get into the fact that everything you perceive is already in the past.
