"TES 6 will suck because it might not let me ignore/promote slavery "
Genuinely, the guy is complaining that the game, that we know practically nothing about, will probably give you a questline to liberate slaves.
At the most basic level (I.E. role-playing as an evil character) I sort of agree. But, like, they're not going to force you to do the whole quest. Ignoring the prompt is the evil option. If you ignore the questline, the slaves remain slaves.
The problem isn't wokeness. I doubt anyone would object to the concept of role-playing as an evil character. Hell, it can even be beneficial to role-play as an evil character, as it can provide insight into what motivates evil in the real world. Bethesda isn't trying to take away evil options because they have a woke agenda. Bethesda isn't going to give us evil options because Todd Howard is an idiot who believes having broad gameplay is the same as having deep gameplay.
If Starfield is anything to go by the ways of resolving the quest will either be to leave the slaves where they are or purchase the slaves, with the slaveowners being unkillable despite only being in that one quest.
It was off puting and kinda showed a lack of vision and like honestly the fact the economics of Astroid mining crashing the market because of the sheer amount of supply in a rare earth astroid being an example of how space breaks the frame work of supply and demand. Full stop you need to be able to imagine something more even if capitalism still exists in some way.
