Where in Europe do you consider islam to be more than a ‘cultural category like Christianity’? Most European countries have large Christian conservative political parties that are preventing trans people from getting the medical care they need and women from having ownership of their bodies when they’re pregnant.
As a trans person fundamentalist Christians are a much bigger threat to me than fundamentalist muslims. I experience solidarity from muslims who know what it’s like to be marginalised and discriminated against. There are muslim people who would like to restrict my determination over my own body, but there are way more Christians in my country who would like to do the same and they pose and actual threat to me.
