This article from Feministing is an excellent example. Under US law, foreign organizations that the federal government provides anti-AIDS funding must oppose prostitution and sex-work. Now, feminists and sex worker advocates are complaining that this is discriminatory against prostitutes.
On Tuesday, July 20th, NSWP organized sex workers and allies to disrupt a speech by United States Global AIDS Coordinator Dr. Eric Goosby to demand justice for sex workers harmed by PEPFAR’s discriminatory anti-prostitution loyalty oath.
To be fair, it's not just liberals who are at fault for their incessant use of "discrimination." Conservatives who care more about ending racism and sexism than limiting government are the prime reason that liberals get away with this.
