I hold an extremist view that the war on drugs should end now, with all the drugs banned made legal to sell to anybody over the age of majority in that country (so 18 in the US) and anybody serving time in prison for any drug crime be released immediately.

People usually shut that down in a way that makes it clear they haven't considered the point and don't respect the opinion. It does not make me question that opinion, it makes me despise them more. Where twitter to stop permitting discussion of drug laws, I would not change my mind.
