(The ad, one of three, is part of a campaign called We-Consent, run by the Dublin Rape Crisis Centre (DRCC).)
Extract only:
A spokesperson for the Department of Justice said the videos were "produced by DRCC at low cost using volunteers and are not part of a government advertising campaign".
Meanwhile, Dr Eoin O'Malley, an associate professor at Dublin City University, said he believes the advert is the latest example of the state overreaching.
"You are seeing people pushing ideas that are beyond mainstream," he said.
O'Malley said that the importance of consent is reasonable to most people, but that the video is too extreme.
"The idea that there needs to be an ad telling grandparents that they shouldn't hug their grandkids, that they should look for permission in advance of that, seems absurd to most normal people.
"The Irish constitution is very clear that the family is the primary unit for teaching children and for raising children, and so to some extent this is kind of going beyond that."
However, the campaign has its defenders too.
Academic Dr Órfhlaith Campbell said it is not an attack on grandparents but instead aimed to highlight the importance of consent.
"The ad is highlighting differences in children's needs and the imp (sic) of consent. It is not campaigning against grandparents. Dear god in heaven!!!" she wrote on X, external.
An account named Danny Boy said it wasn't "discouraging grandparents from hugging children" but was "encouraging children to speak up" if they feel uncomfortable.

I remember this being a very active discussion a few years (decades?) ago so am surprised by this reaction.
