Why 'They' Is No Longer Just A Plural Pronoun

This is a teen-written article from Community High School newspaper in Ann Arbor, MI.

As the world which we live in changes, so does the language which we speak. Bitch, the term for female dog is now a degrading term for woman. Queer, which used to mean odd or unusual, is now becoming the new umbrella term for the LGBT (Lesbian, gay, bisexual and transgender) community. Words that used to be acceptable can now be considered offensive, and vice versa. Still, even with the fluidity that takes place within the English language, strict rules remain intact. Rules that have no alternative form and cannot be broken without seeming grammatically incorrect.
