I think Basque Country is blackmailing with violence.

As long as they search independence by killing others, they do not deserve it.

Bombing people to bits and pieces on the streets of Madrid , or any other town, village etc, is pure anarchy, and it has to stop.

Only then can negotiations start, basques have issues, but whether they warrant independence is totally a different question, and has nothing to do with basques left leaning ideologies.
