We need to be careful throwing around terms like "anti-Semite" - especially when referring to people from the past who cannot defend themselves against the allegation. The historical context matters a great deal too. Much of the evidence for Disney's alleged anti-Semitism is based on the "guilt by association" assumption. Any German filmmaker of the 1930's for instance pretty much HAD to be associated with the Nazi Party to even be in business! Disney's associations, and whom he visited/consulted with do not necessarily make him guilty of anti-Semitism any more than me having associations with Atheists would make me anti-religious or "anti-Christian." The list of comparisons could go on. Negative stereotypes concerning Jews were indeed found in Disney pictures - especially the shorts. That's not a point of dispute. However (and this is important), if you look at the cultural/historical context, this sort of thing was practically everywhere. Does this make it right? No it doesn't...but we must be aware that even Warner Brothers had films and shorts with negative Jewish stereotypes - and the head of Warner Brothers at the time was Jewish! Would we call him an "anti-Semite" as well? I don't think so. Perhaps Disney had some anti-Semitic tendencies, but we must be aware that if we judge many of his contemporaries by the same standard, so did they. This leaves us with a large number of otherwise decent people we must now decry as anti-Semitic and bigoted because they don't meet our modern criteria and/or they had associations with people who didn't meet our modern criteria. This leaves many people from the present as well! So, why all the fuss from me about this? "Anti-Semitic" and "bigot" (as well as some other labels casually thrown about) are strong terms. They can be reputation-destroying and can pretty much damn someone in the eyes of the public - who often don't do the research to find out exactly why someone was affixed with that label or if the strong term is really appropriate given the situation, time, et cetera. I would advocate tempering the use of these strong terms...especially with an otherwise decent man like Disney.
I hope I'm thinking properly about this and not just being contentious or nit-picky. The "other labels" I alluded to are the oft-used "racist," "homophobic," and "sexist," and the less-frequently used labels "misogynist." Also, the prefix "anti" is easily and often applied to nouns and adjectives in a way that immediately puts the recipient of such a label on the defensive. The point is, these labels, in our contemporary climate, immediately put someone on the defensive because they are so toxic. They can be reputation-destroyers. They are an easy weapon. You'll find some of these terms dispensed when an argument is failing and the person losing needs to stop the quickly staunch the flow of blood (figuratively speaking) and quickly gain the upper hand - not with a good argument, but with argument-stoppers such as these. For the good of all concerned, and with an eye toward truth rather than just cheap victory, we need to be careful how we use these words. God-willing, I will practice my own advice.
