[40K] What is the Imperium of Man's overall attitude towards homosexuality?
gpt
The Imperium as a whole doesn't give a shit about small issues like that. You pray to the the Emperor (how you name him or how you honor him is up to you even), you pay the Tithe, provide some regiments of IG and you are good.

The whole rest of governmental work is left to the individual worlds. On one world homosexuality might be persecuted on others openly practiced. Despite looking like a homogeneous Empire from the outside the Imperium is culturally very diverse.
