I think the 'centrist'-cum-'Grown Up' spectrum goes (left to right):
1. Communist mong
2. Socialist mong
3. Centrist
4. Centrist
5. Centrist
6. Moderate Conservative (centrist on social issues)
7. Hard-right mong
8. Far-right mong
9. Extreme-right mong
10. Mong mong
It's not literally standing on number five and thinking the Holocaust had its strengths.
