seems similar to the set up for systemd snippets, where you can avoid changing default config files for systemd units and instead use a drop in file in that created .d dir to load and overwrite the defaults on boot for whatever specific thing. don’t know anything that uses this for bashrc, tho. most likely harmless, especially if there’s no created bashrc.d yet.
the ableist part is saying you must be crazy if you do a violent thing, when reality shows the mentally ill are far far more likely to be a victim than the perp in a violent crime.
edit: also, ya know, this whole thread of ‘probably autistic’ speculation.
