Actual supporters of Trump correct me if I’m wrong but I think they’d say “you’re afraid because the left has deliberately promoted hysteria and fear; the things you’re afraid of aren’t going to happen”. Like, I think they legitimately do not believe that someone could be scared of Milo because they are scared he’ll say their name on stage and then they’ll be beaten or strangled or deported or murdered over it, I think they model fear of Milo as ‘the left has deliberately self-modified to find anyone who is not cowed by leftist orthodoxy terrifying’.
So yeah, they don’t believe you (or they believe that your being scared has almost nothing to do with their behavior). Unless you or your loved ones are an undocumented immigrant or a refugee, in which case I think they’d say ‘well yes I am endangering your family but I don’t have an obligation to endanger my family to protect your family”.
This is not exactly encouraging but I think it’s roughly a description of the thing.
From the Trump supporters I know, this is reasonably accurate.
