The Taoiseach has condemned a protest outside Tánaiste Leo Varadkar's home, describing it as a 'dangerous trend'.
A small number of far-right and anti-vaccine protestors took to the street outside the home of Mr Varadkar on Sunday, prompting garda attendance and widespread condemnation.
Speaking to reporters in New York, Micheál Martin said the protest was wrong and would discourage people from joining the political process in the future:
"There's no necessity for that kind of aggressive protest in a residential area. To me, it's a dangerous trend — something we don't need in Ireland."
The Taoiseach also said that social media videos of Covid-19 patients being urged to discharge themselves from hospitals was "reprehensible".
"We'd have heard anecdotal stories and people have been encouraged to they're having to go back and even more severe.
"Covid is a very serious illness and has damaged quite a lot of people in terms of long Covid. Many people have been very shook by Covid for a considerable time afterwards. It's not your normal flu. You should avoid trying to get it if you can. If you get it you should treat it very seriously. And that is my advice.
"It is outrageous that anyone should, in a very ill-informed way, advise people to leave hospital.
Mr Martin said he had "touched on" the issue of the burgeoning far-right and anti-vaccine movement in his discussions with New York Governor Kathy Hochul.
"In America, for example, the anti-vaccine campaign and other agendas have been very strong and led to fewer vaccinations. And politics became part of mask-wearing, vaccination and other debates.
"In Ireland, we've been fortunate that that hasn't been the case by a significant cohort. In many ways, the very robust public debate that we've had in Ireland and the role the media has played in giving a voice to the articulation of experts and academics has helped us to deal with this.
"I would worry over time that as online becomes more influential, that those kinds of protests would act as a disincentive to get into politics, will make it difficult for people and make it difficult for people.
"I'm a great believer in parliamentary democracy and the ballot box. We should uphold that."
