'The Writers' Union of Canada deeply regrets the PAIN and offence caused by an opinion article in our member publication, Write magazine. The Writer’s Prompt piece offended and HURT readers, contributors to the magazine and members of the editorial board.'

That's an excerpt from the press release the Writers Union put out, emphasis mine.

There's plenty I don't like about social justice warriors and their take on the world, but one of the worst is their intentional conflation of 'offense' with literal pain and injury, as seen above. Being aggrieved isn't enough, because people tell them to get a thicker skin or to do what adults do and turn the page, change the channel, ignore, walk away, etc. They have to be HURT.  Who would be so heartless as to ask an injured person to ignore their injury?  

It's basic emotional manipulation because they want to leverage the power to censor the offender. Walking away just isn't good enough. They need to punish.
