Everyone is clowning on you, so I’ll try to give an answer. Left anarchists take direct action to help marginalized people. They recognize that they live in a capitalist country and cannot overthrow it overnight, so they take collective actions to protect the vulnerable and disrupt the plans of the powerful.

I don’t speak Greek and I’m not an anarchist, but I imagine these fellas wanted to show this capitalist that firing women for the crime of being pregnant would have consequences for him.
