This book isn't about clothes, but free will. It explains why we should not pass moral judgement on people.

{{Free will by sam harris}}

This book explains very well why I believe judgement should be practical and that moral judgement is both harmful and makes no rational sense.

One argument that I find compelling is this. Either events have causes (this is known as determinism) or they don't (this is randomness). If an event is the result of determinism then it was not free. If an event was random it was also not free. All events either have a cause or they don't and neither case is free. If there is no free will there is no cause for moral judgement, only practical. For example, criminals should be separated from the rest of society because they are a likely cause of harm, not because they "deserve" punishment. Practical judgement, not moral.

Ask yourself. "Is anyone's choice of clothing causing objective harm to others?" I think you will find that the answer is no. Anyone who thinks otherwise likely thinks this because they take it on faith. The harm they believe results from clothing depends on supernatural judgement, not reality. They are the source of any harm, not the person wearing whatever they like. If there is no free will and no God to judge you, what harm can the clothes you wear cause?
