Exactly. And people are entitled to their choice to make stamps like this.
Likewise, people can choose to leave the page and ignore it. They don't have to take it personally and get mad. This is the internet. This stamp isn't assaulting anyone in-person.
If someone is so easily offended that a dumb stamp like this ruins their life, then for their own sake, they should just stay off the internet. The internet isn't going to cater to someone just because they're overly sensitive.
