(Ditto for left-handed people to some extent; less of a thing these days, but there _was_ a time they were kinda treated as an outgroup in many places.)
Here's one of the many ways the Open University answers the question on what politics is:
Among the broadest ways of defining politics is to understand it as a ‘social activity’ – an activity we engage in together with others, or one through which we engage others. Politics, in this sense, is ‘always a dialogue, and never a monologue’ (Heywood, 2013, p. 1). A similarly broad (or perhaps even broader) definition is offered by Arendt (2005), who argues that politics does not have an ‘essence’ – it does not have an intrinsic nature, or an indispensable element according to which we can definitively, and in all circumstances, identify something as political. Thus, there are no quintessentially political acts, subjects or places. Politics, rather, is the world that emerges between us – the world that emerges through our interactions with each other, or through the ways that our individual actions and perspectives are aggregated into collectivities.
