I think it is interesting you identified language as the problem, I don't explicitly disagree, but I think there might be more to it than that, I would have to reflect on that a bit.
The point is there is knowledge humans are capable of having which can't be acquired through science. You can argue that the limitation derives from the language science is using, but ultimately science is still incapable of communicating this knowledge. Nobody is saying it is a problem which is unique to science, but it does undermine the view that science can teach us everything.
I am confused, do you think philosophy can't be based on empirical evidence? If not, then what is your objection to calling unfalsifiable theories philosophy of science? Do you have a coherent argument as to why it is more appropriately called science than philosophy of science? I feel like I have made a pretty strong case for my view, and nothing in your response has really undermined that case.
It would be nice if you could defend your viewpoint here, as opposed to just making an unqualified assertion that my view is "backwards". I advanced an argument in favour of my own position, it is intellectually dishonest to fail to engage with my argument at all and assert that I am wrong.
EDIT Somehow I missed this:
Would you care to tell me why it isn't true? You promised a response 4 months ago that I am still waiting on. It should be noted that I am specifically claiming some aspects of theoretical physics are more correctly called philosophy of science than science. Contemporary philosophy of science requires a serious amount of science literacy, I would expect anyone of influence in the field to hold a BSc or higher science qualification. For this reason your objection makes little sense.
Moreover, it seems that your reasons for rejecting my position are entirely sentimental. Please prove me wrong and actually engage with my argument, instead of simply declaring to other people that I am wrong.
