In Germany, Die Linke is anti-capitalist and advocates "actual socialism" and current has 39 MPs in the Bundestag.
In France, LFI (France Unbowed) is anti-capitalist and advocates "actual socialism" and currently has 71 MPs in the French parliament (second largest party by number of MPs...). There are also several smaller parties that are more "hardcore", including the historic French Communist Party that still has 8 MPs and 14 Senators...
Now I do agree that social democracy is not socialism, but again, plenty of socialists in Europe, too.
On a related note, when people claim that they are "anti-capitalist" (which seems to be more popular than claiming to be socialist) it does not really leave many alternatives, just semantic flavours of socialism.
