You need to put your weed down for a bit and let your head clear. It is axiomatic that if all those serial killers were pot users, then all those specific pot users were serial killers.
Clean your light bulb, bub. Even if every murderer smoked pot, that doesn’t prove every (or even most) pot smokers are murderers... what kind of craziness is this, maybe it rivals that of smoking pot.
if all those serial killers were pot users, then all those specific pot users were serial killers.
Which part of "almost" did you not understand?
Then, by the same logic:
If all those serial killers were pot tobacco users, then all those specific pot tobacco users were serial killers.
Ergo tobacco likewise produces serial killers, and ergo tobacco should likewise be illegalized.
Q.E.D.
If you like, you can also substitute "milk" for "tobacco."
