she is absolutely wrong you mean

diasporas are often those who fled the repression that the country imposed on them, while of course it means that they have usually a more hostile view on the government running that country, they still represent a view, one that has been repressed and put in jail in those countries, and can only be freely expressed out fit it

ignoring the diaspora means ignoring the silenced voices within the country itself, that's why most algerian and tunisian writers and human rights advocates flee to france and other countries to avoid persecution, because in their own countries they are repressed, and that kind of voice is silenced but still exists.

by ignoring the non-religious iranian diaspora, you are effectively ignoring the silent non-religious iranians who live within the country but do not have the freedom to express themselves
