Custer deserved what he got
I saw this on a sign at a (anti)Dakota pipeline rally. I told the holder that that was a bad sign. He recited the history behind it -- and there is a strong argument Custer did deserve it -- I believe so but that’s another discussion.
In the poor white rural community I grew up in, in their ignorance of history, they would read the sign as celebrating Indians killing whites. There a a lot better things to say such as “Keep oil out of our water” or “Respect our religious freedom.”
We have to be careful of what we say. Too often I see signs which we see as celebrating, but others see as insulting their world view.
We must remember that many (most?) Trump voters are not deplorables, but persuadables.
