A couple of general thoughts:
1. The idea of abstaining from kosher foods that are primarily associated with goyishe cuisine is borderline ridiculous. The vague pronouncement that this spiritual concept is “brought down in seforim” is wholly unconvincing and plays manipulatively on visceral emotions. I don’t give it any weight at all.
2. I disagree on a fundamental level of abstaining from a food because the brochoh is difficult to determine. Study the halachic sources, weigh the various opinions, come to a conclusion, and defend it. In short, pasken, that’s why a Rav has smicha; to rule on an issue, not to waffle on it.
