Ah, I remember back when I was a YouTuber who would comment on posts such as these.
Oftentimes I would take responses to these one step at a time, responding first to one sentence or group of sentences, then the next.
If you must reply, what a lot of this boils down is explaining why these don’t contradict Scripture, and explaining that just because something isn’t mentioned in Scripture doesn’t mean it’s bad, so basically disproving Sola Scriptura. I find that this kind of thing makes for good apologetics practice, but that may just have been me, and if it makes you start to have doubts, it’s probably not healthy for your relationship with God, and it would be wise to avoid reading comments, particularly from comments purposed to be hostile, as this person wrote, and rabidly anti-Catholic.
I do understand though, that reading comments can become a habit, and it seems that you are a lot like me in the sense that you have a solid desire to defend the Faith. I find that highly commendable.
