Nobody tends to mind mod / admin biases until it affects them personally, me included. Nobody wants to change it, it just keeps getting shifted to "oh, you can't rely on that guy? then move over to this community, you can totally rely on this other guy".
Don't you guys realize mods and admins are better and smarter than you guys? That's why you shouldn't have access to see the votes like they can, that's why it's you who needs to leave a community instead of just being able to opt to different moderation, that's why they can call you out for behaving a certain way and then ignore it when people who support their stance do it.
News and politics tends to attract opinionated participation and the people who want to manipulate or constrain them to their own biases get attracted to moderating those communities. My advice is to ignore the masks people put on and look at how, how many, and under what biases they are actually moderating under.
