"Catholics believe that a cracker magically transforms into actual human flesh. I promise you, that is out of line with reality."
It doesn't sound pretty crazy when you haven't grown up with it, but on the contrary, I can promise YOU that it is perfectly in line with reality. I'm glad you brought this up. There's so many Eucharistic miracles out there I probably don't even know half of them. Just off the top of my head, I know about one that happened in France (maybe?) where two men with mortal sin on their soul took the Eucharist anyway and spit it out because it burned their tongues. Where the Hosts fell on the stone alter, they burned their imprints into the rock, and you can still visit the church and see them to this day. Many Hosts have bled, and one even turned visibly into actual human flesh. It was examined by a doctor, and they discovered that the flesh was cardiac tissue. I think they've even found Jesus' blood type by examining the blood that physically, visibly turned to blood on an alter. There's plenty more but those are just the first two that come to mind.
"The Old Testament says that women are inferior to men in numerous places. And the New Testament says that women are inferior to men in numerous places."
Where? Men and women are inherently different and play different roles in life, but they are both equal in dignity.
"Many Catholics (and Christians in general) treat women like baby machines, like that's their purpose in life. And are women allowed to become popes?"
That's part of many women's purpose, but not all. We have nuns, and they're celibate. No women are not allowed to become popes, or be ordained in any way. That doesn't decrease their dignity in any way though. Priest is an inherently fatherly job, partly because Jesus was a man as well as all His apostles. That doesn't mean He didn't love and respect women though. Some were of His closest friends. And Catholics honor Mary, the Mother of God, more than any of group has honored any other woman in history. No man (besides Jesus, who is also God) has had as high and as important of a role as Mary had, a fully human woman.
