Als „Nutznießer des Gesundheitssystems“ habe ich am Samstag Patienten im Altenheim behandelt und am Sonntag stundenlang Bürokratie für die Praxis erledigt. Diese Bezeichnung ist ein Schlag ins Gesicht aller im Gesundheitswesen Tätigen. Und nein, ich werde das nicht verzeihen.

Jason Arday, ein schwarzer Professor der Uni Cambridge, hat sich das Leben genommen, nach einer medialen Hetzjagd mit klar rassistischen Untertönen. Die Qualität seiner Arbeit kann ich nicht beurteilen, aber wenn jetzt so zu tun, als sei Rassismus hier kein Thema, ist das peinlich.
