Are we really observing an aveirah? Each individual is a unique, separate world. Everyone has their own way, and it's a good way. The mistake: I love all Jews, even though their way is "wrong!" All (halachic) ways of avodas Hashem are beautiful in His eyes. When a child has a different way from the parent. Different issues are important in different generations. The idolatry of worshipping "my way." Making fun and demeaning something that's different.
