It's not just hundreds of years ago.
Witch hunts continue to this day around the world, with devastating consequences. These are as painful and blood-soaked tropes as depictions of central Asian or African peoples as violent barbaric tribes and races. Sensitivity is not a bad thing. Nobody's taking your game and tropes away. Full stop. Some of us ARE discussing why WotC is avoiding the class in name only and thus answering the OP's question, "So where my witches at?" Literally nothing changes if you want to rename the Warlock the Witch class, or use another class to tell a story about witchcraft. But please don't try to pretend the history here isn't laced in violent, sexist, toxic masculinity that led to the murder of countless women (and other persons) across the world, and STILL IS HAPPENING.
