Respectfully correcting one's elders

Q: What should a person do when they are unnecessarily scolded or taunted just because they speak the truth or cant stand injustice and those doing so are one's elders in authority? Should a person speak up when he finds some wrongdoing or be numb and don't react and be a hypocrite for the sake of survival in a negative environment which unfortunately has become common in our modern society. What does Islam say about it as there are many people who deal with difficult ones either for the sake of jobs or family peace and work.

Making a mistake in tashahhud and repeating an aayah of Surah Faatihah in salaah

Q: I have few questions regarding my doubts and sajdah-e-sahw

1. If I performed sajdah e sahw already and then I recited attahiyaat again and committed mistake in the second part of the shahada i.e. (wa ash hadu anna Muhammadan abduhu wa rasooluh) but not corrected and go to durood shareef and while reciting durood remember that I committed mistake in shahada so I just recited the second part of the shahada again and then recited the durood again, is it permissible to recite the mistaken part only or do I have to recite the full shahada again once I reach durood shareef ?

2. If I repeat any ayat of Surah Faatiha, not the full surah or any part of attahiyaat and not the full attahiyaat, does sajda e sahw become wajib or not?

Marrying a Christian

Q: I've been working in corporate company for a few years, and have met a girl there. We both really like each other. She however, isn't Muslim. She's a Christian. She really has a great relationship with God. But, she doesn't have intention of converting - even though she's considered it a number of times.

Her ideal way of raising our children up would be to teach them both religions, and focus on their similarities. I will also always put Islam first, but, if this is allowed, I really don't want to let go of this girl. We really get along well, she's intellectual, she's a few years younger than I am, and we both love talking about religion and life in general. Similar interests. Please advise me as to what to do.
