I somewhat disagree, Jews are a pretty good way to snap people into the zone of noticing things they have psychologically repressed which is essentially what Liberalism is designed to accomplish. You can start with Israel and Jewish lobbying groups which number in the hundreds, the history of Zionism movements in the West, the fact that while both main parties cannot agree on what gender is or if borders should exist both agree that Israel is the most important thing ever to American identity, these are safe ways to introduce the topic. In the larger sense, everyone on Earth knows Jews are weird, neurotic, perverted, and control certain huge industries. Go to the heart of Vietnam or the Congo and they're probably familiar with this.
One of my favorite clips was on Stone Cold Steve Austin's podcast where he was interviewing some fat Jewish wrestling guy who made a self-deprecating joke about Jews controlling the media, and Stone Cold earnestly chimes in with "yeah so what's up with that, you guys controlling the media?" and suddenly the tone shifted. Everyone both behind and in front of the camera had to reel it in and he got kinda scared all of a sudden. Which is to say: everyone is looking for a window to bring it up as long as they're assured it's safe.
