I respect the Catholic faith. I was raised as a Catholic. I have become an evangelical Protestant - but I still regard Catholics as Christians. I have reasons for opposing some Catholic practices; and I hold some real doctrinal differences with Catholicism, but I in no way regard the Church as a whole as anything but Christian and believers in Jesus Christ.
In short, they are my brothers and sisters in Him.
I hope that was OK. I gave as completely honest an answer as I could.
I do have an uncle who is a bishop in the Catholic Church, though.
It was ok with me.
