A Green Party councillor has said she has received threatening phone calls and been targeted online by people accusing her of "hate speech" and censorship.

Hazel Chu, who was elected to Dublin City Council in the Local Elections last May, said she was sent a video clip on Twitter in which a protester referred to her as "that migrant".

The protester also said she was curtailing people's freedoms by saying hate speech was wrong.

Speaking on RTÉ's Ryan Tubridy Show, Ms Chu said she had lived in Dublin and Kildare all her life.

She said she called gardaí over the weekend after receiving the threatening calls while she was at home with her one-year-old daughter.

Following the video, she said, everyone felt like they had a right to discuss if she was a migrant or not.

Ms Chu said: "I thought, well if we are going to have conversations and discussions, we need to bring facts to the table and it was factually incorrect. I've had a lot this week of what I can and can't say and people saying 'oh you're trying to censor us'.

"This conversation isn't about censorship. When you talk about people, when you have discussions, the debates, you need to be factual, they need to be true. We need to stop spreading lies and misinformation."

She said there was speech that was causing people harm, such as questioning someone's sexual orientation and questioning if someone's race was superior than another.

In response to the tweet, Ms Chu wrote that she was born and raised in Dublin.

She said the feedback to her reply accused her of not being Irish and that she had no right to discuss or tell people what to do.

After that, she said, someone overseas was tagged and it became a global issue.

"Someone with a lot of followers, with around half a million followers and well known for his right wing views, tagged me in and I was receiving hundreds ... of messages discussing whether I should be sent back to my own country

"[They were] asking what will happen if people did this in China, why do I not advocate for a mass immigration in China ... that I had no right to be here and that I should respect the country that has given me a home, or free housing was another one."

She said that a petition was then started to say that she was a racist, because they claimed she was belittling Irish people and telling them what to do.

Ms Chu said she was told she did not belong in Ireland and admitted that she found the whole situation baffling.

She said she was not playing the victim and was not the only one experiencing this on the streets around Ireland. She said people should not be allowed incite hate like this.

Ms Chu said ignoring the comments and threats does not work and it was a form of bullying that, she said, was growing in Ireland and internationally.
