For what its worth--here is my 2 cents ...
First, much of what you say is true. We are a bunch of old (well...aging) men who sit around here in our spare time and debate arguments largely centered on science vs faith. Many of us are highly educated and know the science.
Critical thinking is encouraged. Biblical Creationism is often attacked and creationists are challenged to provide evidence.
But let me address your situation. Sounds like your parents have a traditional faith outlook on life, yet are not extreme apart from that. As is normal, you rebelled against being a mere clone of your family and became agnostic while you sorted out your feelings and beliefs. Quite common at age 19. I respect that you stuck it out as long as you have...and implore you again to spend more time studying. Also, humble yourself and ask your parents to forgive your tirade...they only want to see you humble and not proud. What they have taught you, while not scientific, is real...it comes from the heart and soul, regardless of whether you end up a believer in God and the Bible or whether you continue to question it. They sound like decent folks and I will pray for you and your relationship with them.
The guys here have thick skin and challenged you without knowledge of your internal conflict between emotions and facts. They all want to teach younger people (as well as older people) how to think dispassionately about science and methodology...they are in no way attacking you personally unless they are teasing...which they sometimes do.
My advice? Love your parents and study hard. You are on the right track, whether you end up being a scientist, a teacher, or even a pastor.
Perhaps you came here not to learn about the ToE or science, but to resolve the cognitive dissonance you felt existed between your parent's faith and your own questions. Be honest with them. Tell them that yes, you can be a stubborn one but you have no intention of disrespecting them or their beliefs.
They love you regardless, I'm quite sure. Carry on...and study hard!
