overgeneralize

verb

Etymology: From over- + generalize.

1. To discuss or regard something in terms that are too general, and thereby ignore significant details or differences.

   “And — again to overgeneralize from my experience — users may not want a second Twitter either. I was a heavy Twitter user for over a decade. I loved it until I didn’t. I made connections, grew a following, floated ideas, had fun. But it also became a second, often angry, voice inside my head. Do I want to replace it with another one?”
