When I see this posted about certain people , it angers me so much

"THEY WERE ALWAYS NICE/KIND TO ME"

It does not vindicate the person and you're belittling the experience or trauma that others may have experienced, you're high and mighty opinions are traumatising to others, so maybe hold up and think before you go around spouting how such and such a person was always lovely/kind or whatever, or how their illness excuses their behaviour.
