Brief answer
Why do you hate cyclists?
I do not hate cyclists. I dislike being passed at speed on a walking path with little warning, especially when children are present. A bell helps when used early.
Cars are worse. That does not make every bicycle harmless.
For comparison
Canada geese have documented warning displays: head pumping, an open bill, hissing, honking, and vibrating neck feathers. A goose will warn you.
That is the complaint. The rest got out of hand.
