What right to do you have over others?

You don't have the right to force others not have or have an abortion just because you say so. It should be up for each individual to decide, it doesn't violate your rights or theirs.

As for the "its murder" argument, they same thing could be extended to masturbation. Hell, they could become little kids, stop commiting mass murder!
Or women refusing to give any, they are killing a perfectly possible child.
Sure its a stretch but it operates on the same principle of that could become a live child. (It still isn't alive until it can breathe on its own)

But I really can't see why this is such a contreversial topic.
