“…For these reasons, we have become drawn to the idea that some of the powerful identities that map out the fault line of action include identities based on opinions about how the world should be (Bliuc, McGarty, Reynolds, & Muntele, 2007;McGarty, Bliuc, Thomas, & Bongiorno, 2009;Smith, Thomas, & McGarty, 2015). An opinion-based identity is an identity as a supporter or opponent of a particular issue, for example, as pro-versus antiglobalization (Cameron & Nickerson, 2009), pro-life versus pro-choice (Ntontis & Hopkins, 2018), or as "Remain" versus "Leave" in the Brexit debate (Hobolt, Leeper, & Tilley, 2020;Van de Vyver, Leite, Abrams, & Palmer, 2018).
