May you all have peace!
I would [have to] tell them:
"Your parents are doing the best THEY can, based on their own upbringing and what they know/don't know. They're imperfect. That's irrelevant, however, so long as they are not physically abusing you (in which case, we may need to contact the authorities). While you are a minor, therefore, and living in their house, eating their food, and using their electricity and water... you really should do what they ask of you. The Most Holy One of Israel WILL bless you for it.
In the meantime, you can go to JAH, through Christ, and ask Him to grant you "wisdom and knowledge" so that you will know how to walk in your life with your parents... until the time that you are living on your own. If they insist you go to meetings, go to meetings; "honoring your father and mother" will only result in blessings to you. While going to meetings may be hard, the fact that you are obeying your parents... honors God. He will NOT forget you for it.
"Once you have moved out and you are on your own, however... once you are eating your own food, from your own table, paid for with your own earnings/money... then you should feel FREE... to look into what it is that you believe... and/or don't believe... and why. And if you find fault with it, or need more information regarding it, then, again, you can go to JAH, through Christ, and ask Him to grant you "wisdom and knowledge" so that you will know how to walk the remainder of your life. This is NOT a "dishonor" of your parents, for you are still obligated to care for them, should they need you to. However, you are no longer under their "law"... but under your own... and can now make decisions for your life."
Any parent here who says they would condone someone teaching their child opposite to their "law"... is not being truthful (I am not speaking about those things for which you have no or neutral conviction; I am speaking of those things for which you are immovable - and every parent has them). To help... or even tell... a young person to dishonor the "law" of his or her parents, to ANY degree while such one is still living under the parents' roof... dishonors the Most Holy One of Israel. Instead, we can pray for such young one... and ask for help on his/her behalf.... through Christ... and let HIM handle matters for that young one.
God is not so unrighteous as to let a young person, who is doing what he/she can to obey his/her parents, be held accountable for the "laws," decisions, and requirements of such parents. They... will have to answer for their own error(s).
I bid you peace.
Your servant and a slave of Christ,
