Anhand von biographischen Interviews zeigt es, welche Konstruktionen von Geschlecht bei M{\"a}nnern vom Leben in Eritrea, {\"u}ber die Flucht durch den Sudan und Libyen bis zum Ankommen in Deutschland von Bedeutung sind. In der Geschlechter- und Fluchtforschung lag mehrere Jahrzehnte der Fokus auf dem Leben gefl{\"u}chteter M{\"a}dchen und Frauen. M{\"a}nner kamen meist nur als T{\"a}ter geschlechtsbasierter Gewalt vor. Inzwischen existieren zwar einige Arbeiten {\"u}ber das Leben von gefl{\"u}chteten M{\"a}nnern, allerdings wird meist nur das Leben im Ankunftskontext betrachtet und M{\"a}nnlichkeit im Singular gedacht. Flucht erscheint so als eine Marginalisierung von M{\"a}nnlichkeit. Dass dieses Verh{\"a}ltnis allerdings weitaus komplexer ist und vielf{\"a}ltige M{\"a}nnlichkeiten in unterschiedlichen Beziehungen zu Flucht stehen, ist die zentrale Erkenntnis dieser Arbeit.}, language = {de} } @misc{LoeckmannSchneider2022, author = {L{\"o}ckmann, Teresa and Schneider, Matthias}, title = {Geschlechtergerechtigkeit im Verbraucher_innenschutz?}, series = {Genderblog}, journal = {Genderblog}, publisher = {Zentrum f{\"u}r transdisziplin{\"a}re Geschlechterstudien an der Humboldt-Universit{\"a}t zu Berlin}, address = {Berlin}, year = {2022}, language = {de} }
