Indeed. I think a more useful definition is someone who does not exclude either side, from the set of people whose needs politics should address. Let's call that an 'ethical moderate'. Left and right could be thought of as differing in whose behavior they think needs to change, to improve the world: the wealthy and connected, or the poor and disconnected. The more hardline you are, the more you think that that behavior doesn't just need to change, but is reprehensible and deserving of exclusion from consideration. So you can be an 'ethical moderate' without necessarily holding centrist opinions. It may be that this means it should be named something else, but I think it's a useful way of thinking.
