I'm from Greece. I've heard numerous stories from the victims themselves, the ones that managed to survive. This is all true and just the tip of the iceberg.
It happens to the Evros river as well where people from Turkey come from.
There was a shipwreck in Pylos with hundreds drowned last year.
And there are many cases from people that are rescued that later are returned or tortured.
The ones that manage to get a staying permit as official refugees, are treated by most government offices with inequality and lies.
Calling bullshit, given you made an emotional argument with no backup and coastlines are protected on an individual basis it is unlikely there is coordination in their law breaking
There doesn't need to be any coordinartion, since the ideology comes from the top. Their job is to stop brown and black refugees, so being a white suprematist is not only a personal ideology but a job requirement.
You are defending willful negligence that leads to the deaths of migrants.
Up to 1 in 13 migrants die in the Mediterranean. Italy as well as Greece have been allowing migrants to die as a part of deterrence-based migration policy. Rescuing the passengers of capsized migrant vessels has been criminalized. There are plenty of articles that confirm these facts. Here is one example.
While I agree with your statement, there is also a difference in how awful we are, between allowing capsized vessels to just take their course and if we deliberately throw migrants overboard, as this post says is happening in Greece.
