That's because historically illiterate people who are right-inclined call anything they don't like "communist" without having any understanding of the real meaning of the word.
I believe you're confusing communism as a form of government. It's a theoretical concept, it's never existed in nature. It's a useful term to help "socialism" sound like the less scary side of the coin, but Socialism isn't anything special, just feudalism with god traded for the all powerful state. Doesn't matter if a god or the state choose the representatives, you're still are owned by those entities, and those that claim to represent them. Fascism is also a funny word for feudalism too, means the same thing. I think your confusion is focusing too much on the flowery justifications of absolute power as a distinction, rather than the government's actual role in the respective people's lives.
4 years ago? are you kidding? The biggest single erosion of individual rights and privacy in the last century in the US was the Patriot Act, introduced over 10 years ago during the presidency of George W. Bush.
I'm going with military draft (aka 1940 Selective Services Program) for the win. Thanks for playing "Biggest Single Erosion of Individual Rights and Privacy in the Last Century in the US!!!"
I consider being forced to fight and maybe die, slightly ahead of W & Crew looking at my net porn and listening to my 900 calls. Ole pussycat Bush? Please, he was a C student, not even close to top of the class for eroding Constitutional rights, not even the last hundred years. I'll add Federal Income Tax, Commerce Clause, Social Security and Prohibition to bump your Patriot Act way further down the list of biggest erosions to our rights here in the USA.
If wer'e just going by the 21st, you're not even close either. How about the government forcing people to shop with the Obamacare thing? If health insurance was sold at malls, we'd all be required to go there, and buy stuff at the insurance stores. Some people may like the idea state imposed medical services, but it's still a huge erosion of personal rights when you're forced to buy ***** or the king can have you fined then imprisoned.
There's also that thing about the government being able to kill American citizens they don't like without trial, which totally bypasses every single right they have under our Constitution. Peeking at vs. killing at... pretty obvious distinction there. Maybe there's a lot of similarity with the draft thing, but that's a bigger, fresher pile from Obama than any Patriot Act.
*I also thought you'd enjoy if I threw Obama in there somewhere. Since you put Bush in your post, figured you liked putting faces to policies, or liked playing with Presidential action figures or something. Maybe you need another figure for your 'bad guy' team? Hope all this helps!
