Dave Knight, Jack’s dad, has lived in vans for five years.
He said he was surprised to learn that some people have been using the Downs “as a toilet”.
“It’s totally unacceptable and I understand why the council want to move those people on,” Mr Knight said.
“But, to move everybody on because of one or two people – if you had one or two people being anti-social on a street you wouldn’t move everyone out on that street, you’d find out who it was and rectify that.”
He said moving the van dwellers will only move the problem elsewhere, for example into residential areas.
Jack added: “There’s not really anywhere for me to go.”
