Cathy Brennan is a Radical Feminist who believes that transgender women are not women, and calls them 'fake women'. On her Twitter, she has “goth” in her bio, in retaliation for her views on transgender women, someone asked her if she is a fake goth. Since that tweet the transgender community began to widely share the phrase "Cathy Brennan is a Fake Goth"

Several hundred people have been banned from Facebook for posting the phrase 'Cathy Brennan is a fake goth' or variations thereof; in a perfect demonstration of the Streisand effect; this has resulted in the phrase 'Cathy Brennan is a fake goth' becoming a growing Internet meme that was shared publicly on Facebook approximately 45,000 times in the three days since the original incident.
