Because I appreciate the artwork and I'm not stupid enough to be a patreon to this? Most of the scenes in this are hand waved away with "Well I'm here, the device makes it feel good, so I might as well enjoy it." forcing that viewpoint on a lesbian woman is a whole different can of worms as it requires a forcible conversion of her sexuality. There are lines that should not be crossed and Kate Kane is firmly on the other side of one.Indeed, how dare the villains behave this way, because they must be polite and respectful to others, and carefully choose their words so as not to offend anyone by accident.
After all, they cannot give a damn about what is there and who what can think about their actions.
After all, they did not kill, rape, execute people and living creatures, who may not have respect for the gods or even despise them.
No, definitely not possible.
But seriously:
Kate Kane exists in the DC Universe, so she can be in the game.
Most villains don't care what orientation, opinions, and stance someone else is, if they can be used or they get in their way.
And given Lex's personality in the game, I think he would have found it even more interesting.
If you think the game is "pretty icky", then maybe it is not for you?
