still blows my mind that multiple people can call someone abusive and the response from others is still “well he’s always been nice to me” [I Am Ginger]

I've used that line before, but never in a "ah, he didn't do anything bad type thing".
Mine was meant more so in the way of "never seen it myself".😬lol
Doesn't mean it didn't happen tho.
I've written a post on this though because oftentimes when someone gets a warning people will rally around a lot. Talk about how nice they are. Say how they've never done anything wrong to them.

Being nice in the past doesn't mean you don't do bad things at times in the present. And it doesn't mean you are incapable of it. And no one is ever treated the same honestly.
There is personal bias even if we try not to have it. I try to treat everyone the same personally. There are little differences.

Its the big differences that count I suppose(acting noticeable abusive asf with one person and kind to another). Smaller ones aren't so big of a deal(example being a preference for interacting with one person more closely than another)
