Blunt tools shouldn't be used for complex real-world things. Other examples would be mandatory sentencing in courts (you should let the judge assess the particular situation), or things like "I don't go out with guys under 160cm" (you should get to know him).
Just because someone is in their 70s, doesn't mean they can't lead. Not with any certainty. In some cases it does, but the political process should have the flexibility to deal with each case.
Look at Deng: he was mid-70s to mid-80s when he was in power and he improved the lives of 10⁸ or 10⁹ people.
I generally think all the "Biden is so old!" stuff is pretty silly. The president largely delegates. Yes he makes tons of decisions and some of them must happen quickly. But generally, I do think the president can be an elder.
However. Contrast this with members of Congress. They sit on committees. They have to learn intricate details about the committee topic. They are supposed to pass laws to keep our government current (and then largely the president appoints leaders to execute those laws passed)
Overall, it would be great to have more Gen X and Millenials in office. Specific leadership roles can be filled by the old, as the old folks do gain some things. But when leaders refuse to engage on new topics or refuse to understand why 90% of people under 50 all agree on something.... That's a problem.
Furthermore, he is associated with some of the worst purges during Mao Zedong's rule; for instance, he ordered an army crackdown on a Muslim village in Yunnan which resulted in the deaths of 1,600 people, including 300 children.
It seems like killing a whole village is a pretty blunt tool.
Is that all you have, judging a spelling error? Only a weak argument relies on pettiness. If you believe in him so much how about you comment on his well documented crimes? Or do you have nothing to say?
Deng Xiaoping (Chinese: 邓小平[a]; 22 August 1904 – 19 February 1997) was a Chinese revolutionary and statesman who served as the paramount leader of the People's Republic of China (PRC) from December 1978 to November 1989. After Chinese Communist Party chairman Mao Zedong's death in 1976, Deng rose to power and led China through its process of Reform and Opening Up and the development of the country's socialist market economy. Deng developed a reputation as the "Architect of Modern China" and his ideological contributions to socialism with Chinese characteristics are described as Deng Xiaoping Theory.
PS Not OP, I just searched "Deng political leader" and found the above wikipedia article, the age matches so I think this is the person OP is referring to, but I may be wrong.
Look at Deng [...] he improved the lives of 108 or 109 people
Lemmy.ml? Makes sense. Your supposed hero "Deng" was a maniacal tyrannical dictator that was responsible for the deaths of countless students at the Tiananmen Square Massacre. He was an offender who committed crimes against humanity and he should be treated as such.
Might I suggest you leave Lemmy then, as Lemmy was created by a communist, or did you not know that? Not just lemmy.ml, mind you. Lemmy the software.
I mean, stick around if you want, but if you're going to complain about communism on a communist founded platform, that's like me going on Truth Social or Twitter and spouting antifascism. I'm gonna get some hate in those circles. Just saying.
No one should be in charge of creating laws they won't be alive to see the consequences of. There's very little chance someone of that age is truly in sync with what the average person wants, Bernie excluded. But even he I doubt is fully up to speed with everything. There's so many reasons why it's bad to have people 70+ in charge and since I'm on mobile I'll let others go more into depth.
