It always bothered me a little how the Federation was quite passive when it came to certain things. Especially what they were willing to ignore. It's pretty clear that the Federation values free will a lot. And they want their citizens to be happy. But they seem to be letting Vulcans do things that may be seen as oppressive. Like their arranged marriages. They certainly put a lot of pressure on children to go through with it. The only way out seems to be pretty brutal and even then, it is still discouraged. Also, there is the fact that they think all Vuclans should control their emotions and claim it would be catastrophic and these Vulcans would hurt others and themselves. But, for all their faults, Romulans seem to have a functioning society. I think Vulcans could do without arranged marriages. And they have huge potential for generating problems. Why does the Federation allow that?
