There is a lot to unpack in that article. I could look at it from many points of view, as the situation is very complex and there are quite a few topics discussed.
At first blush, I don't find the general point of the article to be at all surprising.
As NZ has pointed out, and as I have discussed, on multiple occasions, Israel is a very nationalistic country, but they really have no choice. They have built a wall along their border. They have an extremely secure border. They are very vigilant when it comes to the threat of terrorism within their country. Everywhere you go, you see armed soldiers. Soldiers take their automatic weapons with them when they are grocery shopping, or when they go to see a movie.
With those things noted, I don't find it to be at all unexpected that Republicans are on board with the Israeli government. They (you) see Israel as the model for what they (you) want for the U.S. Build a wall! Keep the brown skinned people out! Everyone should be armed to make the country safer!
Conversely, many liberals empathize with the Palestinians, who suffer in poverty, and have no country to call their own. Israel won't let them in, and no neighboring countries want them either. The fact is that other countries are willing to take them, and Israel has offered them portions of Israel, but the militant Palestinians won't accept any of these options, unless their new land includes a portion of (many say "all") of Jerusalem. The Palestinians are good at playing the victim, but many of them are tired of this struggle, and would be happy to work with Israel in a peaceful manner. But, that is a different discussion.
With all that said, there are two different issues being touched upon ITT. One is discussion about the U.S. government's support for strategy that makes the Israel government more secure (an area where Trump is much stronger (the antithesis) of Obama. The other is about the current state of Antisemitism in the U.S. They are two very different topics/concerns, and can not be conflated into just one big issues.
I can recognize that Trump is good for Israel, while being very concerned about rising Antisemitism within U.S. borders. It seems like there is a weekly story involving antisemitic hate crime, or arrest of someone pushing antisemitic narrative. That is why I have been sharing such stories ITT.
You guys are fond of distancing your side from the individuals who are being revealed/revealing themselves as obsessed with antisemitism. "No one wants to be affiliated with those loonies". "that guy had mental illness, and can't be lumped into any political affiliation". "that investigation started 3 years ago when Obama was POTUS". "He said he hated Trump".
However, the fact is antisemitism is on the rise. White Supremacist groups, and the Alt-right are more active and more out in the open than they were 5 years ago. For me, and for many other Jews that I know, this is a scary thing. Personally, I believe that Trump is the main reason for this change. I have explained my reasons a few times on this board. I know that many of you disagree, but there is no point in arguing. You are not going to change my mind.
Do I think there is going to be another Holocaust or a race war in this country? No, I do not. But, I worry that good people will become desensitized to antisemitism/hate crimes directed at other minorities, just as our population is becoming desensitized to school/mass shootings.
