> What kind of writing system allows people to change my words after I've written them?
Any kind of writing system allows this. Translation changes the words, and can change meaning. People can mis-quote. And yes, over time, meanings of words change, as do the cultural contexts from which they came. None of this is unique to emojis.
The truth is that all communication has at least two parties, and there is never a guarantee that the receiver will get the message as intended. Even if you do craft "pixel-perfect" emojis, people still can (and likely will) mis-understand the nuances of your intended message.
