BzyCat,
Pray and study the doctrines/principles involved. When you start viewing doctrine through the lens of "popularity" or "personality", you enter the realm of sentimentality. Let's remember that Church history is full of examples where the "extreme" view was correct, while all others were wrong. Truth matters, not "sensibility" or "reasonableness" or "earthly sense".
.
1. St Athanasius vs Arianism (historians said of the time: "St Athanasius was against the world")
2. St Thomas More/St John Fisher vs Anglicanism (Bishop Fisher is the only prelate to stand up against heresy)
3. Pope St Pius X said he was "surrounded by wolves (Modernists)".
.
Truth is not a popularity contest, which is why so many rejected Christ, even His disciples.
