There is no centre - there never was. Not in a “left-vs-right” conception, anyway - there is no such thing as “half-a-socialist” or “half-a-capitalist.” You’re either for it or you’re not.

There is a way of visualizing a “centre,” though… if you imagine the status quo as a “centre” (which also signifies institutionalized political, economic and social power) and draw a circle around it, everything inside that circle will be right-wing - everything outside it will be left-wing. This would actually be somewhat more accurate than the silly “political compass” infographics which does more miseducating than anything else.
