I know, but I don't think that's really a thing. A leftist is a leftist, you can't be left wing socially because you support same-sex marriage but then support free market capitalism. That's not leftism. That's about social progressivism vs conservatism. Sure, they correlate, but aren't at all the same.
In fact, liberal democracy is the reigning ideology right now, and the main issues are between different flavours of liberals. In the UK the Liberal Democrats, Plaid Cymru, the SNP, Labour (pretty much), the Conservatives and UKIP are all liberals.
