If this is your stance, you should hate the company itself, not the shareholders. The company chose to go public and sell part of itself to shareholders in exchange for getting the shareholders more money over time. There’s no law or anything forcing a company to go public. There are lots of companies the get giant and still remain private. Just some examples:
Cargill - agriculture giant
Fidelity - investment/brokerage
Cox communications - cable/internet provider
Publix - grocer
A company chooses to have shareholders. If you have that hate, direct it at that company that made that choice.
