Strong enough to stand up against it

Yes I know it's been sometime...

The guy that's a Mr. nice guy to everyone is not really a nice guy deep down inside. Just because some one's your friend, it doesn't mean that you need to stick by him or her even when they are in the wrong. Although theoretically it seems that standing up against something you feel is not right is the perfect thing to do, just how many of us actually practically implement it? I'm not implying that you should go against your friends just because they are wrong but rather make them understand and accept.

I'm surprised by those backbone less individuals who just keep sticking up for things that they know are wrong in their very hearts but still do not want to confess it due to vain reasons. Is friendship strong enough to bury intelligence and one's own logical mind? I fail to understand...
