Although the Spanish are usually open and tolerant to other cultures, there are some issues that are best avoided in casual conversation or business encounters. These sensitive issues include, for instance, discussion about the Franco regime, concentration camps and prisons, the Spanish Civil War, partisan politics, religion, conflicts between regions of Spain (particularly Basque, Catalan and Gibraltar), homosexuality, personal finances or questions of a deeply personal nature. Other topics to avoid include bullfighting, machismo and feminism.
