Yeah. Hate can be taught passively. A subtle off comment can leave lasting effects especially when its directed at certain people and their differences. It haunts the impressionable. Their hate grows as awareness becomes twisted reality. Eventually someone that listens to hate does something about it and gathers others to do the same. The idea of hate perpetuates for generations as it becomes us vs them.
So what you're saying is it's not a choice? Especially for more impressionable, less intelligent people? ---
