What's the point? A noticeable heartbeat is one of many developments incidental to growing a baby. It's an arbitrary legal standard in some states. It's not a significant difference. We all start out as just a bunch of cells, a skin tag is also a bunch of cells, it doesn't grow into a person, there is a critical difference. Abortion at any stage is a person that won't be born. You may be pro-abortion but don't kid yourself it's just a clump of cells. You're still a clump of cells, just bigger.
