Agreed, this particular type of person I can at least feel empathy for. Feeling the system has failed and deciding that someone who will blow it all up is better than someone who will maintain the status quo.
I feel that people like your brother are in the minority though and most of Trump's voters like his policies, and so I completely blame them, but that's just my gut feeling, I don't have stats or studies.
I kinda want them here so they can be exposed to leftist ideas and become thigh-high wearing, Linux using furries.
But that's probably just me huffing hopium
