Live and let live vs Enjoin the good and forbid the evil.

Before becoming muslim I was in the camp of live and let live mostly unless it was to try to change things by writing about them or planning to become a politician to change things. Of course there were some things you had to speak up about but for the most part everyone just did their own thing. And then I became muslim and realized by reading the Quran that it is our obligation to forbid the evil. Ok what is evil in most of society's eyes is a much smaller list than in God's and that makes it a lot more difficult. There also is the rule that you must take the person aside to tell them their faults which sounds fair but what about the person's reaction. That is probably why people forbid the evil in public. I personally don't like confrontation and who wants to deal with someone spazzing out? And then of course no one wants to listen to what you have to say and you feel like you are wasting your time plus putting yourself in harm's way but this is what Allah has commanded so you have no say. I must say this is one of the hardest tests I've come across since converting. How do you deal with it?
