The problem with this juvenile and non-intellectual approach is that it negates the merits of any points presented in the argument.
I've seen my own Congressman, Seth Moulton, who has the potential to be an incredible leader, use this approach.
In a Free Society, we must have a free exchange of ideas. Calling people wild and inappropriate names negates the dynamic of this, and is completely ineffective. Present your argument... that is fine. But respecting the fact that others have differences of opinion is the only way to make your own judgments gain acceptance.
More and more, it seems like the adults are in charge again, and the bratty kids are whining and throwing stones.
