That's not what I'm saying at all
I'm simply pointing out that, of the entire cast, only one character is really affected by the Registration Act. That being Bandit, who wants to honor his brother's memory. That's a choice he wants to make, a decision that's personal to him
Mutants are minority metaphor. That's not a choice one makes, but who they are. More often than not, they fall into heroism because they're under attack for being mutants and if racism (and only racism) vanished tomorrow, the majority would simply retire to normal lives. They have no horse in the race, so to speak.
I compare it to the actual Civil Rights era because it's the most illustrative comparison. Yes, many white people were involved in the era, and some died fighting for Civil Rights. But they weren't the ones most affected personally, and they could walk away with the least amount of issues. So yeah, if you're going to do a series about that era, you can't have it be all white people and one black person.
The same thing applies here. The cast was fighting a battle that didn't really affect them (yes, I'm aware Kevin G tried to connect it to days of future past but that really didn't work), and that undermined the series as a whole.
