The word 'javelin' was only one issue he stated, and the only issue that hinged on my wording. His misinterpretation of where their genesis was was his own shortcoming.

I explained what it was and where it came from in two different ways. I used quartz, which is what most sand is, and I used the word silica, also a form of sand. The issue here is that I did not outright say 'sand', which isn't about my wording as it is his understanding of the composition of a beach.
