We have decided some brain quirks are disorders (and get accommodations, as is compassionate), whilst others are flaws (and get slurs). But no one picks their hardware. You cannot earn a better prefrontal cortex or deserve a calmer amygdala. Nor does one get to pick the environment they are born in, which will inform their choices later in life. Even the capacity to “learn better” is a roll of the dice, some brains start the race with sprinting shoes, others with lead weights.
So when we call someone stupid, lazy or insane we are not describing a choice, but simply announcing which kinds of unlucky we’ve decided are worthy of scorn.
Add to the list:
Asshole, cretin, piece of shit, maniac, psychopath, pedophile, pervert, jerk, narcissist, self-centered prick, dickhead, douchebag, and incel.
There’s probably some history behind why people act the way they do. Maybe they were molested as a child, so that’s why they find sex with kids appealing.
Edit: I just remembered I made a similar comment in an Ask Lemmy thread recently.
