What any of us beleive may be of no relevance to you, but then you are not the center of the universe are you? The comments that you quoted were obviously intended for the OP.
What makes an "expert" an expert when it come to faith? No amount of learning the scripture will ever lead one to abstain from eating meat on Fridays during Lent. In any case the layity is as entitled to an opinion on relgious matters as the clergy. We are as able to read, study, understand and seek wisdom.
I don't understand this attitude of "follow every rule or get out". If we had to agree with every plank of a party's platform most of us wouldn't ever vote in an election. If we don't agree with everything the US does in terms of foreign policy, ought we to move? That's insane. Strict, unquestioning adherance to ever rule created by men (not God) is cultish... and most of the nuanced, thinking, intellectual and wonderful Catholics I know are not like that. Jesus set an example of questioning religious authority- check out his dealings with Pharasies in the New Testament. All or nothing adherance to man-mandated (without scriptural authority) religious practice is counterindicated by scripture.
Finally, the nast, rude tone here is the kind of thing that gives Christians a bad name. I would no more snarl about someone else's writing skills than I would stick a Jesus fish on my car while flipping other drivers the bird. Seriously.
eta: OP, I just meant if you are being rebellious to a certian rule, not a great thing. If you don't feel convicted about not abstaining from meat on a Friday, and you've prayed it through, then don't sweat it.
