I'm a liberal, but in the European sense of the word (not the American bastardisation of it, which would be leftist).
So I'm a centrist, socially very liberal in most matters (drug decriminalisation and legalisation, equal rights for minorities, but not affirmative action), and fiscally conservative to an extent. By this, I mean I support, for example, German led austerity measures in order to stabilise the Eurozone (following the fiscal irresponsibility of many countries), and I have come to understand the UK Coalition's efforts to trim back the deficit. Furthermore, I support the model of Ordoliberalism, or the Social Market economy; that is, an economy that is predominantly free market, but regulated so that competition is kept fair and not oligopolistic. The purist laissez fairez approach, espoused by many libertarians, I find leaves the predatory aspects of the free market all too sharp.
I'm strongly secular, even slightly anti-religious, and support strongly equality of opportunity. Certain policies of the left, such as the universal provision of healthcare, I also support fully. In foreign policy, however, I am hawkish, and while this could be construed as a right wing perspective, I see it as a 'liberal interventionist' one. Namely, I believe that the West should not neglect it's role as the world's focal point of power, and should be willing to intervene if and when necessary to preserve and improve lives abroad. To do otherwise would be callous.
Finally, I also find efforts to reform backwards electoral systems (such as FPTP) a priority, and strongly support proportional representation. Entrenchment of civil rights, too, I find an admirable and excellent goal, in countries where this may not be so e.g. the UK.
TL;DR: 'radical centrist', very socially liberal, fiscally conservative, liberal interventionist, internationalist, secular.
