It's not? The distinction escapes me. Where have you been the past 30 years? Pro-choice is nothing but a weasel-worded Orwellian obfuscation for pro-abort.
Think about all the things that you wouldn't do or encourage others to do yet you think should be legal. Does that make you pro-adultery, pro-alcohol, pro-cigarettes, pro-rap music, pro-voting for Democrats, etc.? Of course not, and conservatives' inability to recognize that distinction hurts their cause and just makes them look like idiotic zealots.
ABORTION a bad word even to abortionists.
