Who's fucking asking for a solution?! Things can be reprehensible without needing a direct "solution".
As for Neeson's specific case, like we can start to hypothesize how we'd stop random revenge thirsty white dudes from searching for black people to kill, but that involves acknowledging toxic masculinity and racism not "thought crimes" like y'all are implying lmao
The point of his anecdote isn't racism, or toxic masculinity.
Its about most humans having the capacity for great evil. Black people do heinous shit. Women do heinous shit.
e: and I'll tell you for free, way more people
think about doing heinous shit than ever actually follow through and
do that heinous shit.
The moral of this story isn't 'don't have bad thoughts'.
Its 'never reveal you have had bad thoughts publically, because you'll get hounded as though you had actually done the thing you thought about'.
Which itself is fucking terrifyingly toxic.
