Yes indeed, to each their own. The singular "they" can be confusing in certain cases, but that's not really a problem unique to "they". "He", "she", "it", "we", and "you" can all be confusing in relatively common circumstances.

But you're going to have to get used to the singular "they", because it seems to only be getting more common (historically, singular "they" was acceptable until the late 19th century, so the strictly plural "they" might be seen as a 20th century anomaly).
