Yes, unfortunately or fortunately, depending on one’s perspective, liberal “preaching” at his Reform synagaguge drove him to covert to Roman Catholicism.
The result was he became a borderline anti-semite, and a flat-out hater of zionism and Israel.
Funny. My background in a Reform (and then a barely Conservative) synagogue led me to avoid all synagogues for years, but now I’m a member (and on the board of trustees) at an Orthodox synagogue.
But no matter how I felt about the Reform branch, I never even considered being anti-semitic or anti-Israel.
