"Others argue the former employee’s freedom of expression made the dismissal unconscionable"
People can say anything they want - no one is gagging them - but words, like actions, often have consequences.
I wanted to know his motivation/the context... seemed an odd thing to say. A wire article has the police (he was arrested and charged) stating that he:
"did not give any reason for such a post but casually said 'I just felt like posting it'. He was very casual,"
Thd Twitter thread that kicked this off, started by a chap to alert the man's employer to the post, stated:
! What kind of Islamic Terrorists are working in your organization? It's really unsafe for other employees.
sir, please fire him right now.
It also has screenshots from what appears to be his social media account.
His profile picture has a 'spread the word to end the word' logo, a 2018-19 US campaign to stop people using the word 'retard' as a slur.
The thread continued with most people assuming he was a dangerous Muslim terrorist, presumably on account of the assertion in the post and his Jihadi-chic look in his profile pic. Thankfully, no one called him a retard.
The thread has 30 replies, 121 retweets and 284 likes.
My take, based on nothing but a cursory Internet search and bias, is that he was just trolling for his own amusement - to get a reaction from people - and is now surprised that a country with widespread anti-Muslim sentiment reacted in a way that didn't provide him with any amusement at all.
