It was interesting how your description of thought crimes depended very much on geography and demographics, and i certainly believe that these factors affect the extent of how seriously the government responds to peoples' thoughts and actions.
From my personal viewpoint, thought crimes are frowned upon in Malaysia, and there has been severe clampdown by the authorities on anyone who tries to incite 'instability' within the country. The examples that you gave such as converting to certain religions and publishing pamphlets are viewed as direct threat to the ruling body and as such dealt with swift and punitive actions. People are thus 'muffled' and have to be very clandestine if they are ever to voice something out that is not agreeable to the government. But this does not solve the problem, in fact it only gets worse. When you look at different countries,especially ones with totalitarian and despot rulers, the people suffer in silence. North Korea's decision to strengthen its military actually makes its citizens one of the poorest in the world, but yet they cannot do anything about it. When people are refused the chance to speak, the whole country suffers.
As far as I know here in America,freedom of speech is protected vehemently. People are not allowed to say anything they want, but mostly they are not restricted by anyone, and if they are, there are legal and constitutional rights for them to seek recourse. I guess in a way it all relates to democracy and other forms of government. People should definitely be let to speak their mind as much as possible, even though the outcome may not please everyone. Like Winston Churchill once said "democracy is the worst form of govenrment, but is it the best one we've got"
