I do not know about Kilgore but ,without reducing nastiness of some of citations, some are without real names. Like -
Isreali Prime Minister (at the time)
No name of prime minister, only at the time?
There are numerous others ,with name, but without source.
Some are totally lame - chairman of commity to re-election of Tel Aviv major? Really top politician figure. I assure you that there are racists in
Israel, so bringing some obscure figure saying racist/evil stuff is not hard.
Some are , as far as i stand at least,really normal. There really were no suh thing as Palestinians as self-identificated Arab national movement in
Palestine- not in 1960s (then allready it was real) when Golda said it of course, but in ,say, 1930s.
By the way, you must know that the same amount of racist/stupid/disgusting stuff can be found everywhere.
