first of all, the simplified Chinese characters set is NOT a communist invention; attempts made to simplidied Chinese characters date back to the ROC reign, and almost exactly the same character set was adopted as 一简字
Secondly, many of the characters are not invented after all. Some are from simplidies Kanja used in Japanese(e.g.国), while some are colloquial alternatives used in ancient times(e.g.叶). Among those invented by scholars, the simplification is very consistent; e.g . 汉、难、鸡 etc
Thirdly, simplified characters are standard characters used in Mainland, Singapore and Malaysia. I have not heard of a single case where people using simplified characters are looked down upon; neither have I seen people using full characters on the forum of Peking University.
It's true though full characters are commonly used in trademarks, on signs, and in calligraphy, but hardly anywhere else in life. Although any educated Mainlander is able to read text written in full characters, they are too hard to write. Have you noticed that some characters look like stains of ink when displayed on a screen using font size of 20 or under? They have TOO many strokes.
And, please do not go political. You are looking at China with prejudice at best. Mao Tze Dong was a power hungry person, you are right, he had become an Emperor by the time he died. But famine cannot count as mass murder, and even counting the people died from famine it doesn't make up half of the number of people Stalin or Hitler killed.
The literacy rate of Mainland China is 96%, while the literacy rate of HK SPR is 95%. Tell me again that 95% is greater than 96% by a lot. And has it occured to you that with the introduction of Simp. characters in Mainland the literacy rate basically skyrocketed? This was the motive and effect of simplifying the character set. Concerning your idea that its purpose was to shut out democratic material from HK and ROC, I'd like to point out that educated Mainland Chinese have always been able to read Simp. and Full characters, while uneducated Chinese back then could read neither. Even if they were thick enough to distribute paper based anti-communism material in the Mainland, introducing simplified characters is by far less effective than strengthening border control.
May I point out to you that everything you say must have a source of information other than your imagination?
