Is that anyone with a pulse can get up on his/her soap box, and preach to the world how things should be.
The fact is, opinions are like armpits. Everyone has them, and they stink.
And another fact: Even the wisest youth have little to offer in the way of teaching, especially when their elders are on the receiving end!
The Jєωs at the time of Our Lord didn't allow anyone to be a "Rabbi" or teacher/preacher until they reached the age of 30. Our Lord had many good reasons for delaying the start of his public ministry until He had walked the earth 30 years.
Note: Our Lord never criticized this custom even once, even though He criticized everything else in need of criticism.
I've meet many great trad families, homeschooled families, etc. and some very smart, well-educated, and polite young men and women. But even they have a lot of life ahead of them to experience before they will be able to teach anything to those older than them.
It takes a while to develop actual wisdom. It grows more quickly if one's life is in order (the Faith, practicing virtue, abstinence from the modern world, abstinence from excessive media, good education, time to think, etc.) but there is a secondary, indispensable element that can't be rushed: time/experience.
My point: on a web forum, the rash, idealistic, often extreme 19 year old's ideas are given equal honor beside the wise words of the 50 or 60 year old. It's too democratic.
Maybe CathInfo needs an "age" field. And if you don't fill it in, I fill it in for you :)
