I state my reasoning in the rest of the paragraph.
Her views on drug policy are, I argue, the direct result of her lived experience as an administrator. For Palin, living as she does and being involved in the governance of, her town and her state, meth use is the biggest problem they face in the realm of drug abuse and pernicious community effects.
Marijuana use is relatively harmless to both the user and the community, especially when compared with meth.
Therefore, I am arguing that Palin regards marijuana use as a much lower priority as a law enforcement issue.
I agree with her.
Have I explained my reasoning to you sufficiently?
This is the reasoning that the disingenuous poster and others fail to acknowledge, unfortunately. They are assuming that Palin supports legalization of marijuana (she doesn't) and is condoning the activity (she's not) while ignoring her central argument.
Meth is a true scourge. Ugly, nasty stuff. I have never done it (that I know of!), but have seen some sad souls who have. Evil, wicked stuff that preys on the weak. Jesus would be among them in His day.
