Mark Latham has mocked TV star after The Project host described the shame and confusion he felt as a gay student at an elite private boys' school.
The One Nation leader downplayed Macdonald's experiences at Scots College in 's eastern suburbs by describing him as 'dripping with privilege'.
Mr Latham claimed homosexuals were 'massively over-represented' in the media and it was 'the greatest con job in the history of politics' that gay people were considered disadvantaged.
Macdonald attended Scots College as a rural boarder from Year 6 to Year 12 and while he became school prefect he was also taunted as a 'p****er'.
