Every time the left pushes euthanasia, the push back should be against one of their favorite protected groups: serious violent felons in prison.
That is, propose that since the left wants suicide for good people, why not make it an option for hardened criminals?

Each life term, death row, or very long term prisoner would be given the offer to swallow an extra strength Fentanyl pill.
It would definitely make the left back off for while.
