Not all abortion happens the same way. The method described in the original post is something that does occur. Besides, it’s not just about the method. If you believe that unborn children are human past a certain gestational age then obviously it would be wrong to kill them no matter how you do it
Most abortions aren’t anything like the graphic language people use. The majority are done with medication in the first trimester. Procedural ones early on use suction, not “ripping.” In rare later cases, tissue may be removed in parts because of size and safety, but those are a very small percentage, and usually due to serious medical reasons. They are misrepresenting how overwhelmingly most abortions happen to be the extreme minority… its misleading on purpose.
