This whole thread is litzanos, with a touch of ama haaratzos and dishonesty to spice it up.

Halacha can change if it becomes a goyish act. Bamos being the classic example.
But, i hear so here is a non-halachic example:
Having grown up with it, it never occured to me that there could be anything wrong with it. Every year we joyfully wish each other “have a gut yontiff” It was just part of the family tradition.
Then, this year not long after the a hearty gut yontiff I happened upon an opinion price in one of the frum magazines bemoaning the fact that yom tov has become very similar to other unrelated holidays which stands for the exact opposite values.
I came to the realisation that wiching each other “gut yontiff” are indeed chukat hagoi , so my question is; how do I return the assur bhanaha greetings without offending the givers?
