It's interesting to read the responses from people from different ethnicities and countries. A lot of peoples' perceptions are influenced to some extent by their racial/habitual society. I'm Chinese by heritage, born in Taiwan, Australian by choice. Reading what people have replied on this post, I just wanted to add something into the pot for people to think about.
To Chandler (C111): as a Chinese person, I've always thought that it was good China has gotten strong. But, you say that Tibet and other "regions" are part of China and that all the ethnic groups are Chinese. Are you Han Chinese? Are you treated the same as the Tibetans in Si Chuan? Do you have more opportunities because you happen to be in the majority group both politically and racially?
Don't forget, China was weak and taken advantage of by some of the Western Culture for a centuries. Although not taken over and colonized, China bowed down to the more powerful. One day, Tibet may gain the upper hand over China, or other nations may overpower China again. So I suggest to you, broaden your mind and don't just think like a middle class Han Chinese (and yeah you do think like that because as you say, you can't even access a simple website with a different point of view, so I highly doubt you have read widely and have a big perspective).
To Makeumyne and Relokou: many people across the World who fight for Tibetan rights/freedom have no idea how much China has improved and done for Tibet. Before Chinese helped lay down infrastructure and governance, the Tibetan Lamas, the Dalai Lama and the other 3 Lama leaders from the different schools goverend. When the Dalai Lama (DL) dies and a reincarnation isn't found, these 3 other Lamas rule by turn, ie one school rules til the next DL is found, then when the DL die, the next school rules. You can see sorta imagine how much chaos and politics can go on (note that all these schools DO have their own agendas, hence their existence). The Chinese government eradicated this process, and has kept continued progress (this is a western measurement by the way), by building schools, creating hospitals and so on, which the Lamas never did. I know it can be argued that the Tibetan people don't want these things, but yeah, like seriously, should they just be disconnected from the world?
In the end, what C111 was trying to say is exactly what a lot of you are saying i reckon. Media is filled with crap loads of propaganda, Western or Eastern. Better to read up from different writers/reporters from all sides of the spectrum and then start telling each other off haha.
ps sorry for the long read
