Wrong.
You have no idea what you are talking about. Illegitimacy is a legal state for inheritance purposes, not religious. The Catholic Church doesn't care about this.
That’d do it. Oh...any non Catholic Christians here (or their kids) considering marrying a die hard Catholic....you best really do some soul searching first. If you have any children, the Catholic church will consider them ALL illegitimate until you CONVERT. Aaaand you will have to have a Catholic wedding. Thems tha rules. No exceptions.

Oh bull hockey. I grew up Catholic and yes, while there are such nut cases that you describe, most Catholics are liberal like Nancy Pelousy and Joe Burden and most Lutherans are far more conservative than Catholics.
“...die hard Catholic...”
Once you’re Catholic, dying is actually fairly easy.
You clearly haven't read the Catechism or the Canon Law.
The existence (or not) of an annulment has absolutely no effect on the status of the children as legitimate. Nor is it intended to. It is entirely a question of whether the previous marriage was valid. And that has to do with the intentions of the parties, not who's Catholic. Now, once you're both Catholic, you're expected to be married in the church, but there's no particular penalty for getting married in a registry office (which is the case in most of Europe).
“If you have any children, the Catholic church will consider them ALL illegitimate until you CONVERT. Aaaand you will have to have a Catholic wedding. Thems tha rules. No exceptions.”
That’s hilarious. If you DON’T follow “them” rules, what’re TPTB gonna do — 20 lashes with a wet noodle?
The Catholic Church recognizes marriages between Catholics and non-Catholics. You are not required to convert, and you are not required to have a Catholic wedding. All that's required is that the marriage be blessed by the Catholic Church, which means you fill out some paperwork and exchange vows.
No those aren’t the rules.
