Society needs to 'pull our horns in' and accept that there is a diversity of opinion.
Thirteen arrests were made over the course of the protests.
Ciara said she believes what happened outside the Dáil was an attack on democracy.
"Democracy in my view is the best system that we have, and I don't like people who attack our representatives who actually have a mandate," she said.
"The polarisation of politics is part of the problem here, that's what's going on.
"There is the far-left, the left, the centre, the right and the far-right.
"Anybody at the moment who's to the right of Trotsky is practically accused of being far-right in this country, and it is a nonsense.
"There are people with moderate views and conservative views, and they're entitled to have them.
"Not everyone who is on the right, or the centre-right, are bad people and demonising people with opposing views is part of the bloody problem.
"That's where this kind of ability to become violent, and to 'other' and to all of that, comes from."
Ciara said people need to be accepting of other people's opinions.
"We need to actually rein ourselves in and pull our horns in and accept that diversity of opinion," she said.
"We accept diversity of gender, diversity of sexuality, diversity in life: we welcome it, except for of opinion.
"Opinion has always been diverse and it is a nonsense to think that we can have some kind of a 'group think' that we'll all be funnelling into.
"It's worse than a nonsense: it's bloody dangerous, it causes this polarisation," she added.
