Lol. A Christian is someone who follows Christ. Denomination is not important. The Bble does not say that anyone has to be a Catholic to be a Christian. I do not know where that idea came from.
Unless you practice abominable acts...
sure it is...a true Christian is someone who follows Christ and does it the way He told us to. He didn't found the Catholic religion so people could choose to ignore it, He founded it to become the way to salvation. All worked pretty well for 1,600 years, then along came the churches of what's happening now and decided that they knew better than He did and made up their own rules....Good luck with that...I'll stick to the church that He founded.
