The singular "they" controversy

This is actually more about writing than reading, but it's connected. If there were no writing, there would be no reading, after all.

I found this article on Facebook:
The Linguistic Turf Wars Over the Singular 'They'

I will say right now that I am in favor of the singular "they." I resisted it for a while; I was taught the generic "he." However, I see the value of "they" as opposed to the clunky and cumbersome "he/she."
