I'm not into the idea of trying to go out an convince people of anything if it doesn't directly impact me. I see that type of behavior as disrespectful and selfish. However, if I'm discussing topics around an idea I would like to promote, I do mention the idea to see what their interest is. If they seem interested, I will go over the benefits of that idea. If they're squarely against it, or have zero interest, then I'm not going to spend precious time and energy on them.
