IMO we should try to condition ourselves to not dislike things that don’t affect us or the society negatively. I have seen topless people on beaches and ladies in burka and it hasn’t really created negative feelings in me. My conflict resolution training helped me with that. We tend to like people who are like us but with conscious effort we stop disliking people who may be different, we may say nothing but if we dislike someone our body language, expressions, tone etc makes it evident and also it creates negative feelings in us.
