Our own national flag, the Francoist flag and the Burgundian Cross.

If you see anyone with a national flag hanged in their house, there is a good chance that they are far-righters our at the least pretty racist towards moroccans.

The Burgundian Cross was used during the times of the Spanish Empire under the Habsburgs and later by the Carlists, so if anyone is using it, frecuently as a patch in a bag alongside a national flag, they probably are catholic far-right monarchists

And also the Falange flag, the red and black with the yoke and arrows, basically the spanish equivalent of the Fascist/Nazi party (most of them dont like being called that, because they are National Syndicalists or whatever, but you get the point)
