Not to come off as an a-hole, but if your only link to judaism is from your father's side, you aren't jewish. Sorry to burst that bubble, but judaism comes from the mother - meaning if your mother is jewish, you are jewish. If your mother isn't jewish, you can only be jewish if you go through the process of conversion.
And no, jews aren't considered a minority even though they make up a very small percentage of the population. And in terms of law, jews are far from under represented.
