Dismissing any individual because they are a member of a group you disagree with is prejudice, full stop. Fine to say you don't want to be indoctrinated, or won't buy double-glazing, but as long as it's a person, that's a fellow-human being.

All kinds of conflicts and problems start with the 'us-versus-them' model. Most people here dislike crypto-racism and prejudice in any form until someone they disagree with stands on the doorstep. Go figure.

I canvassed for nuclear disarmament in the US in the 1980s. Some people abused us, some people agreed; I had a lot of human respect for those who disagreed (or in neighborhoods where the feeling was violently pro-nuke) but were gracious.

Last time the mormons came, I said you can have a cup of tea and visit as long as you don't try to convert me. When we talked, I realized how young they were, how far from home, etc. Very decent lads.
