I did. Facebook also spent a lot of time dumping stuff in my newsfeed from people I wasn't friends with (Twitter also liked to do this). It was a lot easier to just not have all that crap in my life.
An act of unfriending someone is interpreted as hostile action. It's much easier just to not be there in the first place.
Why did you put up with racist and misogynistic people on your feed? Why did you feel the need to delete your account instead of unfollowing people?
My feed is nice and clean, with family, some friends, and some pages.
