In the present Convention, genocide means any of the following acts committed with intent to destroy, in whole or in part, a national, ethnical, racial or religions group, as such:
The intent and type of group being targeted are also part of the criteria.
In this case it would be Israel intending to destroy, in whole or in part, Palestinians. Which South Africa is trying to prove in court using statements that Israeli politicians have made and the actions of the IDF.
The intent is the most difficult element to determine. To constitute genocide, there must be a proven intent on the part of perpetrators to physically destroy a national, ethnical, racial or religious group. Archive of UN.org
I don't think the article you linked is sufficient evidence for her being an islamophobe. Reading some of her history, her opposition to the bill seems based on paranoia that the Iranian government could use it as an avenue to attack her or other women's rights activists from the region.
I say it's based on paranoia because the Iranian government has gone to great lengths to punish her:
She could have been wrong about the bill, the Biden white house put out a general statement of support for it, and it passed in the house, but it looks more like self-preservation based on paranoia than islamophobia to me.
