Conflict of personality

Is calling Shia and Wahhabis non Muslims, calling lavish Quran kawanis (collective reading naats) etc, I am opposed to it as I have believe that Allah should be only one who has right to call anyone non Muslims, and feeding poor instead of calling Quran kawani etc. Recently I had son and after many name consideration, I choose one. Although I asked all so no one is left behind but nothing yet. So I decided to go with what my Mrs and me agree. Now point has come that I can see that my in laws don't like my son's name, and kind of make fun of the name.
