Thank you for your post! And, welcome to Catholicism!
I was a member of a Christian support board for infertility/pregnancy loss/child loss for quite a long time. I met a lot of great women on there. I was also greeted with much “silence” at times because of my username and my signature (which is basically the same as here). I think that there are a lot of Protestants who think that we’re not truly Christian and NOTHING could be farther than the truth.
I stopped posting at that board because I was so tired of how I was being shunned.
And, I totally agree with you that former Catholics are the worst anti-Catholics out there. I can’t tell you the things that I’ve heard from the former Catholics about our faith.
