Other pro-life slogans fit for T-shirts:
Can't find your true love? Perhaps they were aborted.
Ever wished you had a big brother? Perhaps he was aborted.
Ever wished you had a big sister? Perhaps she was aborted.
You could have been aborted, and you wouldn't have had a choice about it.
I'm glad I wasn't aborted!
I'de love to see the commotion from some kid wearing one of those to school.
Thanks, I think I will borrow one of those for a new tagline...
