I suspect there were other reasons why the early 20th century anarchist terrorists (and mid-20th century communist terrorists) didn’t use trucks. Here are two:
1) They placed a higher value on surviving their attacks (and not going to prison) than modern Islamic terrorists. This is more-or-less impossible with truck attacks.
2) They didn’t want to target people indiscriminately but target specific classes of people, namely “bourgeois/upper class oppressors”. The problem with driving trucks into a crowded area is that most of your victims are likely to be proletariats. This does nothing for your goal and alienates the very people whose support want.
I’d really like to see that done with MULTIPLE men and women
So would I, at least this is more than anything I’ve ever seen cited to support the claim.
Except the audience was predisposed to dislike Trump and like Hillary, i.e., the opposite of the ultimate result.
People are always claiming this, but the only ″experiment″ that I know of attempting to test this found the opposite result.
One thing that doesn’t happen with your first example and is happening with your last two is that there are people intentionally obfuscating the gray areas.
Thus a fuzzy boundary is a lot less acceptable.
