Yowza. As an English-language article for a journal which is probably going to have an even higher proportion of English-as-a-second-language readers, it makes your reviewer's actions even more illogical (but then, a German climbing mate's parents used to correct our English grammar whenever they could. Apparently, British people speak English poorly).

I suspect 'anonymous' and 'harsh' are intertwined; this is largely a good thing, though - a pretty robust peer reviewer improves your paper.
Personally, I'd resubmit to the same reviewer with a fairly blunt outline of the parameters for their involvement - 'you stick to the science and let me worry about the grammar'. I suspect most people would just look for a different reviewer.
I'm working on the assumption that this is all pre-publication....
