"prejudices" was a bad wording. I'm sorry to have ignited that much emotional heat which deters from good discussion culture. My usage of "prejudice" was the best kind of correct: technically correct. I was thinking about how nearly everyone that I had a personal discussion with lost their view point about how subsidizing STI tests was a bad idea after I told them about personal experiences of some acquaintances of mine. So those people were (technically) prejudiced, as a close inspection of such cases changed their judgement.

Nonetheless, the word itself has strong connotations and it's mostly neither nice nor effective to tell someone to their face that they are prejudiced. And I can't assume it to be the case about a potential reader of my post.

Regarding whether it is good policy, even with a conservative value system, my sibling comments have already presented most of the points I would make.
