These are accurate, on-target words for the reality of what we are describing. The abortionists prefer to disguise the reality of what they are engaged in by using vague, evasive words and phrases. They have to mask the monstrosity of abortion. It does not sound as barbaric, they reason, to remove fetal tissue, as it does to dismember a live human baby.
Abortionists thrive on such euphemisms and weasel words.
Like things that creep around in the dark, they hate to have the bright light of truth shine on their activities. Many abortionists are embarrassed to admit their involvement in abortion, and they wish to keep that phase of their practice quiet. It is important to associate them in the public eye with their profession. When to use these terms and when not to use them is important. It is not always wise to use the strongest word.
