It is because I see them as fellow human beings that I see them as potential converts. Jude 22-23: "Be merciful to those who doubt; snatch others from the fire and save them; to others show mercy, mixed with fear - hating even the clothing stained by corrupted flesh." (emphasis mine)
It's not because of some sort of intellectual snobbery that I want to convert someone ("I'm right and you're wrong.") but because I genuinely want them to share in the eternal life I have through Christ Jesus. I really do. And I don't think there's anything mean or pushy about that, even if I do hurt some people's feelings by suggesting (gasp) that someone might have a wrong idea (it does happen, you know).
