Labour MP Grant Robertson told the crowd we need to ditch the word tolerance, and replace it with acceptance and celebration.
But Act Party spokesperson Stephen Berry had a different view: "In a free country, freedom of speech is probably about the most important value we have, and so that's why we cannot have laws banning hate speech.
"People like Brian Tamakihas the right to express his s***ty views, and we also have the right to call him out on how s***ty those views are - that's what freedom's about."
A member of the audience then asked Berry: "What about trans people who are told to go kill themselves?"
To which Berry said, "If people tell you to jump off a bridge do you do it? No of course not.
"It is disgusting speech but that is part of living in a free country. And that is why you have the freedom to tell these people how disgusting they are."
This morning Berry is standing by his comments.
"The crowd didn't receive it well at all, which was quite disturbing actually.
"I remember growing up as a kid, well as a teenager, and part of my rebelling was the importance of freedom of speech."
