Why does it matter how I feel? It has nothing to do with me.

I wouldn't recognize it. I've never watched a soap opera.
If it came from a Sci-Fi space opera, good chance I'd recognize it, and think it was fantastic.

If someone changed their last name to “Newman,” “Forrester,” or “Carrington” because they hate their father and his last name and just liked those instead, and legally changed it, how would you feel?

I’d feel like, “Man, what did their father do? It must have been something really awful. I hope they feel better now”. But I’d also feel a bit sorry for them because I’m doubtful simply changing their name would fix whatever damage was done.

I would not notice, and if I did I would not care.

Interesting question. Now, you should know that I have come to think of you as a bit of a friend. Well, an acquaintance that I think fondly of, at least. Don't want to overstep my boundaries here. But there's so many memories we share, all my thoughts about you are warm and tender, I look forward to every new post you create. So in reply to your interesting question, here's another question that has been haunting me ever since I first met you and that I honestly would pay money* to have a coherent, intelligible answer to: why are you never ever satisfied with the answers that you receive, so much so that you keep repeating the same questions?

* at least one unit of [local currency]

I wouldn't give a shit.

Then again, Grim, if my dad was posting about how super heros are bad because they lie to their friends and family, or have a weird obsession about peoples age gaps when dating or difference in family money. Maybe I would also change my name.

I wouldn't feel anything….

There are certainly tens of thousands of people who already have that name.
