I seriously hope someone didn’t suggest that you “try another denomination” on here. Proselytizing for non-Catholic religions is against the forum terms of service. I presume that the post (which if I’m reading the thread right, was by a non-Catholic) has been removed. That to me is really reprehensible behavior, trying to lead a Catholic who maybe wants to return to the church further away from the faith.
Katie, I haven’t responded substantively to your issues on this thread because as several people including me have mentioned, each of them is a thread unto themselves. For example, you saying you believe in “LGBT rights” could mean all sorts of things. Obviously it’s one thing if you simply believe LGBT people deserve to be treated with dignity and kindness; that’s also what the Church teaches. It’s something else if you believe they should be able to get married in the Catholic Church; that’s not what the Church teaches. In addition, Catholics themselves have a wide variety of viewpoints on this particular issue for a lot of reasons. Some Catholics state that they themselves have same sex attraction or are LGBT themselves. Some Catholics have a close friend or family member who is LGBT. Some Catholics simply have a lot of exposure to LGBT people and some do not. Some Catholics agree with the writings of Fr. James Martin and some vehemently disagree.
What I am getting from your posts, Katie, is that you have a very limited exposure to the world of Catholicism, don’t really understand the teachings, and have based your understanding of it on the small subset of Catholics you know from whatever parish you attended.
I completely agree with Phil that you need to at least learn the basics if you’re truly interested in maybe coming back to the faith. Running around to other denominations is only going to muddy the waters, especially since those denominations will want to “recruit” you themself and may tell you all sorts of things about what they think Catholics believe that are likely dead wrong.
I suggested you watch some of Fr. MIke’s videos because they’re directed at young people, they’re short and to the point. I would reiterate that suggestion.
