Parroting opinions

I sometimes find myself repeating an opinion that I heard without giving it much critical thought.

Whenever I tried to voice this opinion on my own however, I was almost always immediately shot down by someone with a better take, leading me to question why I even chose to accept the opinion to begin with.

MSgt said, "Imagine how lethal a platoon would be if every Marine had a college degree"

So I went and told my SSgt, "Imagine how lethal a platoon would be if every Marine had a college degree"

He said that was "fucking stupid and wouldn't mean a god damn thing."

He's right that's stupid and wouldn't mean a god damn thing.

Edit. The college argument is irrelevant, this was about mindlessly parroting stupid opinions
