Another interesting question is this, as a father would you force it on your child to also fan the same club you're a fan to, or you will allow him be himself to fan any club of his choice even if it's your most rival club of all times.
For me I don't think I can force my child to support what I do. As far as I know individual have there right to make their decision. Being a parent does not implies that I must make decisions for them. In every country there is freedom for each individual regardless of who they are. Such freedom could be freedom of movement, freedom of speech, freedom of choice is also included and that is the main purpose of the discussion. So in noshell I can't force my child to fan what I chose to.
