„He is not a stepdad.. he is the dad that stepped up!!“

Greetings to everyone, hope you’re all well.

So the saying above really annoys me, it makes it seem like every guy that doesn’t wanna be a stepdad (people like me for example) isn’t „stepping up“. Like what? I don’t wanna have to care for a child that isn’t mine and that someone else decided to bring into this world. Am I the only one thinking like that? Any thought are greatly appreciated!
