I’m in RCIA, formerly an Orthodox Catechumen, and born and raised protestant in the deep, deep, South. I can say without reserve that most Protestants I know wouldn’t think once about attending an Orthodox Church - much less a Catholic church. However, that’s ‘most’. I noticed recently that the Orthodox parish I had belonged to as a catechumen was chrismating six new members today. And it’s a smallish parish in the deep south. Most of the members there are Protestant converts, and I myself attended - so there must be some Protestants who are attracted (I had to drive over two hours to attend services - and this was done by a good number of parishioners).
All of that being said . . . did I consider Catholicism prior to my journey to Orthodoxy? Definitively not. In fact, I wrote a letter explaining Orthodoxy to some family and friends (hey, it’s weird to most people I know!), and one of the first things I mentioned to allay their fears was, “Hey, calm down, it’s not like I’m going to the Roman Catholic Church.” (not in those words, but that was essentially what I was saying). It didn’t help much

They still prayed for the salvation of my soul, which I appreciated very much - now, I find myself ‘going Catholic’, so I wonder if they regret those prayers.
God bless,
rusty
