"Learning to say “they” for one person undeniably takes some extra effort".

Addressing an individual as "they" is inane and likely confusing.  I am very accommodating, gay positive, transgender accepting but this stupid issue is championed by a small minority of a small minority.  How freaking narcissistic  do you have to be ? 

If you (note I did not say "they", as that would be confusing my meaning as it would seem to imply that I mean all transgender people not just the small percentage of whiners) can't be happy with he or she then how about the already established gender neutral , "It". ?
Sheesh ....
