A jury is relevant to the legal adjudication of harm, not the institutionalization of a certain ideas, activity, etc. as harmful. There are many so-called harms that are arbitrarily declared by agencies as such long before a lawsuit is conceived. Just the same, there are many legitimate harms that states and societies enact as their "right" at the expense of a person's liberty (i.e. conscription, expropriation of property, etc.).
You don't need to take an anti-democracy stance regarding juries.
Also there is a reason why trust in institutions are lower than Trump's approval, institutions are prone to corruptions and enriching the elites while advocating for policies that do not help worker's material needs.
