Because for every practising Catholic or Christian who wears the symbol religiously (take blogger Sami Weaver , for example, who sometimes shares her religious views on Instagram stories and has also worn vintage cross pieces on her page), there are those who are religious and choose not to — whether it's because they're no longer practising regularly or feel there are other ways to express their faith than through clothing or accessories. Then there are those who don't wear it for fear of offending someone, those who wear it to offend and comment on Christianity.
