"Keep you safe" or "stay safe" is an ambiguous and vaguely menacing phrase to keep people in line, a bit like when a gangster offers a business protection in return for a small fee. In order to stay safe, one must avoid things such as
scientific fact,
critical thinking, divergent opinions and basic civil rights. Instead, follow the soyence, and get all your
misinformation fact checked. This phrase used to be known as "for your safety" or "for security purposes".
"We are
installing cameras in all restrooms to keep our
customers safe."
"In order to keep you safe, you must follow our guidelines and abandon
independent thought."
"We want all our stakeholders to stay safe. That is why they will have to have microchip implants to access basic amenities. To keep you safe.'
