You just dont like the way the term makes you feel, when in reality youve probably manipulated people, intentionally or unintentionally once or twice in your life

At worst, its personal attack because you lack any other method to have control over other people

Manipulation is like fire, it can help you cook food or it can burn your house down. Context is key.

You just dont like it when other people are doing it

And youre no longer involved in the matter

TL;DR - What you really dislike about 'manipulation' is how you can no longer manipulate others
