I agree with both these sentiments entirely. I myself was agnostic until I found Buddhism, as the path to the end of my discontent with things. Before I heard some Dhamma talks and started reading about Buddhism, my ignorance had me believe it was another religion based on a belief in some type of creator, god and/or demons etc.
How wrong I was and more than anything this ignorance I possessed and my sudden undertsanding of how wrong my views can be, has led me to be completely open up about things now and let go of my views and opinions. Already this has given me a great sense of freedom.
Once this awareness and understanding sets in, it is hard not to want your frineds to realise also, as the Buddhist approach provides help to all human beings, as we are all full of greed, hatred and delusion. But it is sometimes hard to turn friends away from the Religious concept they have of Buddhism, like I also had. But like the Buddha did, the best we can do is just point to the way and the best way to do this is in our actions. If we seem much happier than ever before, much more tolerent than ever before and much kinder than ever before, then this can't be ignored by our friends for too long...........hopefully for their sake.
