True, while I don't agree with what they're doing, I can respect it because they're doing it in his best interest. But he doesn't seem to be against it so much anyway, so maybe nothing needs to change. But if he isn't he certainly needs to be heard louder 
Remember, they're doing in what they think is his best interest, which might not be what he thinks is his best interest or what is actually truly in his best interest. Those three can be separate and distinct.
Example - A child is a heroin addict (just to break away from the issue of marriage)
- What the child thinks is in his best interest - to get heroin and inject
- What the parents thinks is in his best interest - to hide it and not tell anyone (no rehab) because it'll bring a bad reputation on the child and the family and nobody would want that
- What is actually in the child's best interest - to go to rehab
Get what I mean?

i may even try for med, cause thats wot they want
lol, and will it be you or your parents who pays the price for this decision in 30 years time?
