I didn't say there shouldn't be consequences. For instance, I can understand that Dr. Keyes doesn't want Maya working for his organization, because she doesn't embody the values his organization represents.
On the other hand, except for her sexual choices, Maya doesn't sound like a bad kid. Not every child would defer college for a year to do missionary work, and for another semester to help her father run for office. Maybe she's a bit outspoken and "over the top", but so is her father, just in defense of different causes.
I just can't imagine my parents totally cutting me off, and I can't imagine doing that to my children, either.
Therein lies the problem. You may as well say "that soup looks delicious except for the cockroach swimming around in it."
Her lifestyle is abominable by definition according to Keye's religious tradition.
