FIL making fun of our child’s name

We recently informed my husband’s parents that we have decided on the English and Chinese names for our child. Being Chinese-ed, they complained that the English name was a mouthful, and my FIL even made fun of the Chinese name (he said that people are bound to make fun of our child in school with that name). I WAS SO FURIOUS, but decided to ignore him since my husband didn’t say anything as well. The more I thought about it, the angrier I became. I felt that he didn’t respect us enough as parents of his grandchild. I just didn’t want to rant to my husband because they are his parents after all. Anyone faced the same issue naming their child?
