How to talk about embryo destruction and euthanasia

Reflecting, here, on the state-level election-day set-backs for the pro-life cause -- specifically, the Michigan referendum on embryo-destroying research, the Washington referendum on assisted suicide, and the defeat of a pro-life initiative in California -- George Weigel suggests that: 

We need more persuasive ideas and language in the fight against euthanasia. Yes, the good guys were outspent in Washington State by orders of magnitude -- and that should cause serious examinations of conscience among Catholic philanthropies and individuals of means. But, as in the debate over embryo-destructive stem-cell research, the culture of life has yet to develop a language that trumps the invocation of "compassion" when that's misused by the culture of death.

Any ideas?
