The Born Again Christian rejects infant Baptisms, thus most Catholic Baptisms are invalid in their eyes. In fact, the whole Catholic faith is invalid in their eyes due to numerous errors they say the Church promotes and glorifies. By and large Born Again Christians are not ecumenically inclined at all, and feel a extraordinary need to promote their agenda and beliefs. They do have a genuine concern for your soul though and will generally make extraordinary efforts to convert you especially if you are Catholic. Most, not all, but most believe in the doctrine of the Rapture as well, and see the earth as being in the beginning stages of the end times.
You are painting with an awfully broad brush here, my city has a church counsel who consisted of pastors from all Christian churches in the city. During my fathers time there many invitations were extended to the RC priest to attend and participate. Only when that priest stepped down and another priest attended was the RC church represented on the counsel. The second priest (Father Geneli as I recall) participated fully and even had breakfast many times with my father (a Mennonite pastor). If this is how we are spreading our anti-Catholic propaganda we are really shooting ourselves in the foot!
That being said we do place an emphasis on making a conscientious decision to follow Christ. As most devout Catholics make this decision on a daily basis I can hardly see that a decision of faith has not been made. While there are coat-tail riders, Catholic and Protestant alike (Anabaptist too, I’m not leaving us out) I believe by and large we are all what we call saved.
The really interesting thing about their belief is that once you have accepted Jesus Christ, you basically have a get out of jail free card. Once the grace has been given and accepted, no matter what you do, you are saved. You cannot be denied Paradise no matter what happens.
This is not universally true. My uncle has rejected the Lord and I know it weighs heavy on my mothers heart. We believe that you can loose your salvation but I think we are probably a bit more lax on what constitutes loss of salvation. All in all the portrayal of salvation as a get out of jail free ticket is false. If someone treats it like that it brings into question the sincerity of their decision and the validity of their faith. We believe that proper faith generates works and if one exhibits one without the other it is hollow and good for nothing.
