To be honest there is probably very little difference between those people back in the 1930's and the polarized groups of US voters on both sides of the spectrum. They didn't know at the time what exactly they were voting for and the consequences that would play out.
Bro, I'd ask you to not use the word "jihadi" as a slur. The word means one who strives, physically or mentally, for the sake of good. The fact that it's been hijacked by deviant so-called "religious" groups doesn't change what the word really represents.
And reinforcing the notion that those deviant groups are jihadis just strengthens the claims of ISIS and Al-Qaida that they're the ones properly following their religion, when more than 99% of the muslim world rejects them completely.
If you don't use the term "jihadi" because it's too positive you also should refrain from using the word "ISIS/ISIL" because that gives them being a state and Islamic. I understand that "Daesh" has a much more negative meaning and those guys hate being called that way.
The Clintons assassinated Scalia and they are going to force you to renounce God or put you on the cross.
