Harriet Tighe, lawyer for the GMC, said one post was accompanied by an image of a flag including the Star of David above a swastika.
Munaf also reposted a comment which referred to boxer Floyd Mayweather using a derogatory racial slur.
In a separate post, Munaf expressed sexist views, arguing that certain professions should be restricted by gender and criticised female empowerment.
At a previous hearing, he said the posts were “not befitting of someone as educated as myself and were said in the heat of the emotion”.
He is also accused by the GMC of “disappearing” just hours into a locum placement as a cardiology specialist registrar at University Hospitals Coventry and Warwickshire NHS Trust in January 2024 as he walked out without notice or good reason.
In a separate allegation, he is said to have provided a sick note to a patient in November 2024 while he was suspended from practice.
The Medical Practitioners Tribunal Service hearing continues.
