Can this subreddit have a "Protestant only" flair?

This subreddit is for Protestant Christians. however, looking at the contend here. It seems to be more of a Roman Catholic-Eastern Orthodox subreddit than a Protestant one. This is possibly due to Redeemed Zoomer having more Roman Catholic followers- which makes sense.

I suggest that subreddit have "Protestant only" flair to better fit to subreddit and for a safe space for Protestants.

I'm definitely not saying Roman Catholics should be banned.
