We never seem to learn from history. To start, it isn't taught really so many don't have a clue what to learn from.
I like to compare how our government treated minorities, to how we are being treated now. I was lucky in a way in that I grew up in the country and us dumb hicks were just too stupid to know we were supposed to hate each other, so we talked and told stories.
I was close friends with an Apache whose father had grown up on a reservation, other friends included Blacks and some very colorful Yankee descendants.
Anyway.....getting on with IQ or any other test to own firearms, I'd like to bring up history that was discussed and explained while I was still young and Iggernant:uhoh:
In the late 1800's, our Federal Government adopted Literacy Tests as part of the process to immigrate to the US. Never to waste a silly law, a lot of states realized that since most Blacks couldn't read or write, the Literacy Test was a good way to keep them from voting.
White folks BTW, were exempted....kinda P4Pish, ain't it.
This practice was still going on when I was nearly old enough to vote.
My point is that if the Government makes the test, they control who passes.
Start testing for firearms ownership and only Government approved Idiots will have guns.
As far as Native Americans, they had it a little rougher. They couldn't vote...first because they weren't people, then they weren't citizens. They couldn't own guns until the 50's.
