Ignorant idiots who can't think for themselves will always follow the narrative that is forced down their throat.
See also "The war on drugs". The majority of the people who will demonise you for choosing to use "illegal" substances will also be smashing their livers with alcohol which is more detrimental to both themselves and society than a lot of other drugs on a weekly or often daily basis.
Just because it is legal they feel like they are fine to not do their own independent research into what these things actually do to them and how fucking addictive they are.
I feel like I could probably use that one reference in every other negative thread about the world these days, great game though!
