Robomatic, stooping to rewrite history to support your liberal position doesn't seem to be below you. You professions about those fiddly bits of Marxist dogma are now exposed for all their worth - you have never read anything written by Marx!

Lenin drove a wedge between socialism and communism and this was has continued in Russia and amongst many leftist parties elsewhere, he described socialism as a stage leading to communism. In Leninism and Stalinism there was never an opposition between socialism in communism, hence Stalin called himself, and his party, communist came up with his unMarxist theories of 'socialism in one country' and 'world socialist market'. Stalin did kill and exile Mensheviks, Left opposition and Social Democrats though this had nothing to do with socialism and communism but to do with tactics for socialist revolution (in the former) and allegiance to Trotsky and his equally unMarxist theories and in the latter case those unsupportive of Stalin (the Bolsheviks had previously described themselves as 'Social Democrats').

I'm sure socialists are few and far between in America, they are in the UK too. This is no surprise considering the capitalist ideology that is rammed down our throats from morning and night from birth until death. However, you do have the
WSP(US) and the SPC as well as fellow travellers (by a different route) the
SLP and inevitably a hundred shades of Leon Trotsky.
