Lifes journey has many cliffs and obstructions. Avoidance requires dilligence and a sense of where you are. The path isn't always quite clear. There often is the choice of high roads or low roads, open paths or dense thickets.
Choosing to becomeing intellecually incapacitated is going down one of those lesser paths. It is frequently the drunk who falls off the cliff.
Condeming someone for no offense other than their views and sincerity simply clutters the ability of the accuser to contribute anything meaningful to others, or themselves.
Disagreeing with someones premise, or conclusion is onething, but personal attacks because you cannot offer anything substantual other than an opinion to disprove or change their point is very immature.
