I mean that you cannot expect people to not have a feeling/perspective/reaction.
If you step in a great steaming pile of dog poo, you have a reaction to that. You try to get it off your shoes asap. You might feel a bit icky. Normal. Similarly if we see an old man with a very young/small girl. It's absolutely normal to have reactions and viewpoints. It's great that we are able to express them and to discuss. That IS grown up behaviour.
