socialism is not about peace and love; socialism is about conflict. socialism is about history, and it's a theory of history that describes historical change as a process of violent class conflict. it is an algorithm for the violent overthrow of the state.
the hippie bullshit is actually burkean or voltairean conservatism, or in some cases actually buddhist woo, it's not socialism, and socialists are constantly annoyed and frustrated by people that won't fight for their interests or that won't acknowledge the perpetual class war.
smart socialists know you need to pick your allies (hint: not stalin) and you need to pick your battles so you have some chance of winning. running around amok in africa and ending up in jail for decades doesn't demonstrate much of a useful theory. however, socialism is still always a violent theory of revolutionary overthrow, it is not a peaceful one of co-existence or harmony.
if you want the peace and love, you are really a conservative and should be looking at the literature in the other pile, although there is a sneaky point, in that marx himself often supported conservatives over liberals, despite calling himself a liberal.
