>activism, by definition, includes answering such questions daily.
Yes, I was imagining running into a Catholic in an anti-war, or anti-death penalty, or pro-debt-relief coalition, and having the abortion issue come up. (This isn't very far-fetched at all, since such groups, at least in the U.S., are full of religious Christians.) What should one say to him or her? "Oh, that question's closed, you're a reactionary to bring it up!" With that, Marxism's reputation for dogmatic arrogance wins another convert. Though I strongly believe that abortion should be free on demand (like any medical service, except maybe liposuction), not everyone does, and in politics, few questions are closed.
