The Dutch hierarchy complained about the pogroms and deportation of Jews, so the Nazis seized the Catholic nuns of Jewish heritage as reprisal.

The Catholic nuns were seized from a Catholic convent in reprisal against the Catholic bishops.

Thus her being a Catholic - C-a-t-h-o-l-i-c - was fairly relevant to her death. There is nothing "exploitative" about that. Other religious and priests have been canonized for the same reason.

What I am saying is that canonization is an internal process of the Church, which you reject, to declare an individual among the communion of saints, which you reject, for honor and intercession, which you reject, for those who adhere to the Church, which you do not.

Which also indicates that if an argument could be made, you're not the one to make it.
