When you're, like 2 years old, and you want a toy in the sandpit, you grab it. And if some other kid has it, too bad for them, because you want it, and that's what's important.

Somehow, most people manage to figure out that this kind of behavior isn't appropriate, and hide the issue under the blanket of being-a-decent-human-being.

I don't understand how dealing with sexual or romantic feelings is any different.
