What kind of game was this? I mean if its a game of friends and one guy wants to bring in a family member and the group said no too many players I would find another group.
A dad wanting to share the hobby with his stepson getting turned down would set off huge red flags to me. Frankly I DM almost all the time and I would never do that, even if the group was about to burst with too many.
if the group decided that I would just leave and start a new group.
I love D&D but it's just a game, Family comes first.
It depends on the situation. Family member or not bringing in someone who is rude & disruptive and inflicting them on a group without discussion first isn't cool. Likewise it wouldn't be right for a group to refuse giving someone's family member a chance before even meeting them.
D&D is just a game but if the things we enjoy doing become much less so with the addition of a disruptive player then there isn't much point in playing.
