没有人說芝諾、公孫龍一定是對的，而是在肯定他們的思辨方式的價值, Chinese thinkers or Greek ones. Your fallacy is, you are always more approving of the Greeks.
Back to the questions themselves, Zeno 's paradox can be formulated in different ways and responded accordingly. For instance, taking some quantum theories into account, space really has some indivisible units determined by something called Planck's length. So after all Zeno may not be all wrong!
There are some technical issues in your argument. But this is not the point. Mistakes are OK. It is more important to keep an open mind, not just to the Greeks, but to everybody, your chinese ancestors included. For instance, 惠施 proposed an similar paradox: 飛鳥之影非嘗動也 .
