New research into anti-immigration rhetoric, which I'll try to summarise in this THREAD.
It basically suggests that the emotive use of metaphor & hyperbole in anti-immigration rhetoric drives base support & INCREASES their likelihood of political
Typical anti-immigration rhetoric used by right-wing populist nationalist parties presents immigrants as outsiders, who are framed as a threat to the populist nationalists idealized nation.
In their anti-immigration rhetoric, politicians typically use strong, vivid, & negative metaphors & hyperboles to frame their political statements.
There is agreement that, at least for parts of the electorate, such populist anti-immigration rhetoric can be highly persuasive.
Metaphor & hyperbole can spark emotions by eliciting a vivid image & can increase perceived message intensity.
Metaphors can activate connotations attached to intense & negative concepts, like war & other threats, & hyperboles can exaggerate danger & emphasize threats.
When metaphor &/or hyperbole are used to frame a political issue, they not only add a rhetorical flourish, but they transfer conceptual content as well: they can promote a particular problem definition, causal interpretation, problem evaluation, &/or a possible problem solution.
