一些闲话:
刚读完《伟大的博弈》,确实是一本好书,待我读第二遍时再详细写一些感想^_^
袁腾飞基本上是被“封杀”了,对他基本没一点了解。只是有些话想说:中国近代史直至当代史基本上就是一团浆糊,有人捏造,有人辟谣,有人煽动……而且在一个信息自由获取受限的环境下,片面甚至错误的结论往往传播更快,有些像经济学中的劣币驱逐良币。所以~~~Fuck GFW.
关于69圣战,我也多说两句,孩子们犯错,首先应该被问责的就是家长们,就是当下的社会环境,孩子更多的时候是在被动的接受,孩子犯错了,家长们应该扪心自问自己有没有错误,一味得指责孩子时候很不负责任的,80后也被误解过,所以参加圣战的80后们更应该做出一些思考。
