You omitted the bit just above your quote, which says: >> A palindrome is a word, phrase, number, or other sequence of characters which reads the same backward or forward. Allowances may be made for adjustments to capital letters, punctuation, and word dividers. Examples in English include “A man, a plan, a canal, Panama!”, “Amor, Roma”, “race car”, “stack cats”, “step on no pets”, “taco cat”, “put it up”, “Was it a car or a cat I saw?” and “No ‘x’ in Nixon”. Given the last sentence, doesn't that change the meaning of your sentence to directly refute your interpretation?
