A "thought crime" is where certain thoughts are illegal. My favorite example is from Christopher Hitchens @4:00 - 4:30, worth watching the whole speech.
The defining feature of thought crime is that there is no physical act, no physical manifestation of a crime, just an "illegal thought", accessing a web site or making a speech is an action, it doesn't qualify. Of course in the book, the only way to really find out what Winston was thinking was to torture him with his greatest fear, a live rat chewing on his face.1984 is a precautionary tale about power and control, and there is no more "totalitarian" form of control than the ability to control what people think. You really ought to read it before trying to redefine the terminology.
