If you want an actual answer, I can! Baptists believe that baptism must mimic the baptisms performed by John the Baptist, so they must be believers baptism (no infants) and, most importantly to the meme, full immersion. Presbyterians believe that infants can be baptized and raised in the faith and that any form of water getting on the baptized person (sprinkle, pour, or dunk) is acceptable.
The Baptist thinks the Presbyterian is a heretic, other Presbyterians think this Presbyterian is a heretic if they believe this is the only acceptable way of doing it.
Just because no one in your life cares enough about your niche opinion to actually have an opinion does not make that an “unpopular opinion.” When your opinion is the opinion of hobbyists, professionals, and elites alike, it’s certain not unpopular, even if it is niche.
You’re certainly right in your opinion, and that’s the point of bitching at you.
