Actually, I think the point is that it is rude, and not at all gracious, to announce to anyone you know right after becoming engaged that you hate bridal showers, especially if they are all women, and would not attend if someone threw you one. A wedding, if a couple is paying for it themselves, is their own business. But offering to throw a party in your honor is generally- except maybe for those people who are just attention-seekers- a kind gesture. It’s a ton of work and can be expensive to throw someone a shower.
I don’t love showers either. I also hate attention. My friends know me well, and they threw me a very tasteful and lovely bridal shower at a nice restaurant. We didn’t have any games (which I also can’t stand, but would have been a good sport if there had been any). They were also kind enough not to make it a surprise shower, because I’m not fond of that kind of surprise.
Your friends might know you well enough to not bother with a shower for you, but what if your soon to be mother in law is so thrilled to have you joining the family that she wants to plan one? All of the sudden it’s more complicated than “my way or the highway”. Telling her no and that you wouldn’t attend isn’t a great way to start out joining a husband’s family.
Someone earlier in the thread mentioned that you might find someone so great that all the things you think are hills to die on won’t be so important. I think that’s often the case. It’s also often the case that women who vowed never to give up their careers decide to stay home, or they or their babies have complications that necessitate it. I’d say that if someone is so staunchly against any kind of compromise or allowance for unforeseen circumstances, marriage and raising children is probably not the right vocation.
