An angry mob in Pakistan accused a woman who wore a dress adorned with Arabic calligraphy of blasphemy, after mistaking them for Quran verses.
She was saved by police who escorted her to safety after hundreds gathered. She later gave a public apology.
The dress has the word “Halwa” printed in Arabic letters on it, meaning beautiful in Arabic.
Blasphemy is punishable by death in Pakistan. Some people have been lynched even before their cases go on trial.
Generally, if you keep a low profile, you’re fine. It’s not like the average person will try to fight you if they find out you’re an atheist. It is extremely taboo, though. In my case, most of my friends are left-wing activists and/or artists, so it is not a problem for me socially, but I think I am an outlier in that respect. I do hide it at the office though (or at least I did when I was going to one), and from my extended family, and of course from strangers.
It is absolutely not something you can be public about. If somehow, you become publicly visible and recognized as an atheist, it is best that you flee the country lest you end up in the same situation as the girl in the OP.
