I think singular "they" is OK, although sometimes it is unclear. Magic: the Gathering now uses singular "they", although in the cases where it would be unclear, other phrasing such as "that player" is used to clarify. Since they have considered the possibility of being unclear and made a solution when it is a problem, I think that is OK. I know that singular "they" has been used even since Shakespeare's time. Even "you" is a plural word like "they" is, but is also use singular. Just as "you are", I think they should say "they are" too, rather than "they is". I think is fine using "they" to refer to anyone regardless of the gender or if it is known, or about how many they are or if that is known either, and I think can be useful sometimes that "they" (and also "you") can be ambiguous if it is more than one or not, which is sometimes useful in speech/writing to not specify; is too bad that English doesn't do that with normal words. However, there is also problem other way around: if you want to specify explicitly if they are one or more than one. I suppose if it is necessary, then you can use words "thou" and "y'all" if "you" isn't good enough, perhaps, but then "they" won't. However, I think that you should have free speech. People should try to say what they like to say honestly and clearly, rather than being "politically politeness/correctness" if such a thing is a hindrance (but if it isn't, then it is OK, though). Other people have the right to their opinion too, though, which might not match mine, which is also OK, since it is also freedom of speech. OK
