In this case, I don't think the author is antisemitic. But when common antisemitic themes come up in a text, you can bet that some readers, me included, will perk up and start looking for other ones.

For me (and, probably, many other people), who doesn't daily work with antisemitic pamphlet, ‶secret control″ evokes more some shady secret service shenanigans (à la Hoover files or MK Ultra) rather than a nebulous international Jewish plot :)
The last thing we need is a secret jewish cabal to take all the standup comedians off the market.

There are still a few better runs left.
I get that the language doesn't bother you. But there are plenty of people out there who lost family members due to pogroms brought on in part by antisemitic conspiracy theories. I, and presumably you, are not at the same level of risk, which makes it much easier for us to blow it off. But if your point is, "The experience of Jews reading something doesn't matter as long as I don't see a problem with it," that's a pretty weird stance to take.
