The Vice-President declared pro-life legislation’extremist, and Ms Harris was wrong. Political opposition that is so mainstream as pro-life in opposition to abortion is merely a different, anti[athetic political opinion. Saying the Democrat leadership should be hung would be extremist; anti-abortion legislation isn’t.
There isn’t really a lot of middle ground on abortion any more than their is on murder. One can be pro-life and anti-murder regarding humans at any stage of their life span from conception to joing the Democrat Party and that simply isn’t extremist.
