Luxun's works and opinions are far, far less well known in Taiwan than in the mainland.

Good to know!

You seem to be conflating "someone taught it at a university" with the apparently well evidenced view that Lu Xun's overwhelming coverage in popular media and secondary schooling neglects to point out his anti-character stance.

What do you mean by "apparently well evidenced view?" No I'm not saying "someone taught it at university." That's a public high school exam. That is specifically secondary schooling.

Moreover, this gets mentioned in official publications and popular media frequently. See for example this official article from the Chinese Academy of Social Sciences (which is a state-run entity), which just happened to be the first article that caught my eye.

> 1935年12月，蔡元培、鲁迅、郭沫若、叶圣陶、茅盾、陈望道、陶行知等688位知名人士，共同发表文章《我们对于推行新文字的意见》，其中说：“中国已经到了生死关头，我们必须教育大众，组织起来解决困难。但这教育大众的工作，开始就遇着一个绝大难关。这个难关就是方块汉字。方块汉字难认、难识、难学。……我们觉得这种新文字值得向全国介绍。我们深望大家一齐来研究它，推行它，使它成为推进大众文化和民族解放运动的重要工具。” (http://ling.cass.cn/keyan/xueshuchengguo/cgtj/202112/t202112...)

And my very rough translation.

> In December of 1935, 688 well-known individuals including Cai Yuanpei, Lu Xun, Guo Moruo, Ye Shengtao, Mao Dun, Chen Wangdao, and Tao Xingzhi, published "Our views on spreading Sin Wenz [Latinxua Sin Wenz, i.e. a Latin alphabetization of Chinese]." It stated in part, "China has already arrived at the point of life or death, we must educate the masses and organize [them] to solve difficulties. But the work of educating the masses, at its very beginning already runs into an enormous problem. That problem is Chinese square characters [Chinese characters usually are roughly proportioned as if they were in a square frame]. Chinese square characters are difficult to recognize, difficult to understand, and difficult to learn.... We believe that Sin Wenz deserves to be introduced to the entire nation. We deeply hope that everyone will study them, spread them and put them into practice, and make them into an important tool for improving the culture of the masses and the movement to liberate the people."

More broadly this is a very common topic among Chinese netizens. There are as I linked dozens of forum posts on this across Zhihu, Baidu, etc.

It's not the first thing people learn about Lu Xun. But it's definitely not hidden.

"Hidden" and "not taught" are two different things. I'm not claiming the knowledge is buried in a grand conspiracy, I'm just saying few know because it's not generally shared and this is policy. Source: 20 years of talking to people.
