I'm only comparing it to China by saying this is a slippery slope. Which it is. What if, the old great what if, every country adopts this approach? Should some people be viewed higher or lower in society because of their thoughts? Take neogaf as an example, it wasn't long ago that mods abused their power because of your thoughts on here. Sure it was only being banned from a website, now the government wants to ban people from working? How far is it until undesirables arent welcome in the country at all?
If you see nothing wrong with comments, taken out of context, sometimes years after the fact, affecting what happens in real life, then..well, I don't know what. That level of thinking is alien to me.
I would be interested to hear your reasons why this should be acceptable and what, if any, far reaching consequences you can see or think of?
Show me your point of view, I may be missing something that is keeping my thinking in a narrow field of view.
