Question

why do people avoid derry​

Answer 1

The right name for the city is Derry from the Irish Doire Cholm Chille – meaning the oak-grove of Colmkille. It got the name Londonderry from a company of swindlers that were founded in London, in the seventeenth century, to drive the native Irish off the land and to settle the place with English and Scots

Answer 2

Derry had a burnt face which made him look ugly. That's why people didn't like to go near him and avoided him.
