"They" is the modern gender-neutral 3rd person singular pronoun in American English. You're thinking of the 'Universal He' which is a poetic device of referring to mankind as 'He'.Maybe people should just realize that "he" is the gender-neutral pronoun in English! All you dipshits butchering the language in the name of "political-correctness" can kiss my ass!Then maybe people should just stop assuming and write in a gender-neutral way.
To be gender neutral you can't just assume they're male. And any woman who is willing to endure the sexism and bullish male majority online deserves plenty of respect.
