Why are women invisibile in discussions about nationalism?

Recently, I wrote a post about women's participation in nation-making by participating in secessionist projects.The result?

Silence...not one comment...not even a complaint. Unfortunately this is common  for H-Nationalism. Despite extensive research  that shows

the importance of mass participation by women in  nation-making in countries as diverse as India and Finland, the US and the Phillipines, Scotland

and Catalonia women are invisible in our discussions.  Why is this ?  Or will  silence also meet this post ?
