What issue do some women have against their natural eye brows?

I pluck my eyebrows because I don't like the way my natural ones look. But I do find it kind of creepy that some girls/women draw theirs on. Some people don't like theirs because they're too bushy or they don't look even on both sides. I either pluck mine or get them waxed. I don't draw them on. If you draw them on they look totally fake
