Victims’ campaigner Willie Frazer last night insisted his tweets referring to a Co Antrim school’s GAA PE jersey “were not aimed at the school”.
Last week the Gaelic jersey of St Patrick’s College in Ballymena made a prime time debut in BBC soap Eastenders.
Actress Maddy Hill, who plays Nancy Carter, wore the top on Friday night while behind the bar of the Queen Vic pub.
“I only found out today that it was a school jersey,” Mr Frazer said. “But to be honest that is not the issue.
“When it went onto the internet it was praised by GAA clubs and republican circles.
“This organisation, nothing to do with the sport, is used to glorify terrorism. Until that stops things like this should not be going on.”
Mr Frazer said he felt it was “wrong to see an organisation that is completely anti-British being highlighted in a soap opera on the mainland”.
“Some of the comments on Twitter were ‘if we keep going they will be singing rebel songs’ – and that was what we were replying to.
“It was nothing to do with the school. My issue is with the GAA and how they conduct themselves.”
St Patrick’s College boasts a number of famous former pupils including Liverpool boss Brendan Rodgers and Hollywood actor Liam Neeson.
