Family Feud

I am a child in a family where there is a feud between my parents and my uncles, and they are not on speaking terms for several years already, because one side became offended by the other side and vice versa. The children also did not have a connection, and if any children did want to cross the barrier and speak to their cousins, the parents would shout at us and say that this is lack of respect for parents, and we don’t care about it, and we must not have any contact with them. We don’t even know what happened then, years ago, and we feel intimidated and as though we are criminals if we have contact with them. Is it true that for the sake of respecting parents we must have a feud with our cousins?
