are we sitting good examples for our kids

We can really only do the best we can. Obviously we can't shield them from everything bad for them, but we can teach them right from wrong. I have 3 children of my own (ages 21,18, and 8)and 1 step child, they have always watched tv/movies with us and if there is something inappropriate that they happen to see or hear (my older ones when they were younger) we tried to tell them that the language is not nice, etc. Let's face it, youcan't watch tv, movies or play video games without them seeing or hearing something they shouldn't. We should also try to keep drinking and smoking away from them as much as possible, not that it really happens in todays society, also something they can see almost anywhere. All we can try to do is teach them that it's bad stuff. I hope that makes sense.

well it depends of what are are teaching them and lettting them watch on tv and hope that they are smart enough to not do the things they won't do that we did when we were growing up

It is hard. By the time most people are parents they have their set ways and they may not always be something you want to teach to a child but it is so subconscious for you that you don't realize you are doing it. Trying to set an example by action is a constant daily battle for most parents, at least it is for me. I know that children learn more by what they see than what they are told. I know over the last 8 years my husband and I have had to make adjustments in the way we do things because our daughter would learn by watching us. I take it day by day and anytime I see or hear my daughter doing something that I don't think she should be I ask her where she learned that and if she says me or my husband I tell her that it is wrong and that we will stop doing it also.
