Pre-note: have not read a single post outside of the first 3-4.
Socialism at its base is about bettering society (hence social-ism) through the government. The key to the argument between those who like and those who hate it, is the view of government. For pro-socialism people, the government can help and raise up the people. For others, the government is a suppressor and should be viewed with suspicion.
Yes, the government should play some role. Law, judicial systems, defense, etc. But can we really trust the government? I think recent events throughout the world have shown us that government is flawed, not to be trusted, and inherently not in our best interests, especially the higher up you go.
Government-sponsored genocides in Turkey in the First World War. The Bosnian and other Yugoslav wars. Oppressive governments in Asia (North Korea, China, etc). Even "western" governments are not innocent. Look at the NSA and all the spying going on. Look at the UK and it's harsh anti-porn stance.
The larger the government is (in the amount of people it rules), the smaller it should be (in what it does). In the US, I think the federal government is entirely too large and unaccountable. Power to the states, as it should be.
"The powers not delegated to the United States by the Constitution, nor prohibited by it to the States, are reserved to the States respectively, or to the people."
10th Amendment. Basically, pretty much everything should be state-level.
