The Church is not hopelessly anti-Semitic (although some of recent statements of a few denominational leaders are most obviously anti-Semitic in the extreme).
The Church that follows Christ (and Paul) is grafted onto the Jewish people and salvation is of the Jews. God blesses those that bless the Jewish people, and God curses those that curse them. Any sincere Christian knows this from reading the Holy Bible, it is only a “leadership” problem in some denominations (mostly those that have pretty clearly “gone off the rail,” abandoning other Christian teachings, too)...
What members of those errant churches need to do is replace their sinful “leaders” — or, if that is not possible, then to just walk out the door and find a much more genuinely Christian place of worship (and consider ways we can make up for the damage these bigots are causing the true Church, Israel, and the Jewish people). Fortunately, we still have the ability to do these things in USA (for how long, under our current regime, nobody can say...but that’s a whole other discussion so I will sign off for now).....
