Political Correctness Gone Mad?

‘Without free speech there is no true thought.’

–Jordan Peterson

‘You’re telling me I’m being sensitive, and students looking for safe spaces that they’re being hypersensitive. If you’re white, this country is one giant safe space.’

–Michael Eric Dyson

Is political correctness an enemy of free speech, open debate and the free exchange of ideas? Or is it a progressive force, eroding the dominant power relationships and social norms that exclude marginalised groups from society?
