‘The kindly light will never be defended by nastiness and bitterness,’ Archbishop Diarmuid Martin tells social media pundits and online trolls.

“I want to encourage lay people and Catholics generally to stay involved in social media. You could say it’s a negative environment, there’s a lot of nasty comment, a lot of rough dealings with people. But then we’d abandon that field and let the trolls have it” - Bishop Paul Tighe.
