Some programming languages are blindly deemed “safe” in spite of supporting unsafe memory management strategies, and somehow not enforcing those rules does not render them unsafe.

You’re applying a strawman argument here, because nobody is blindly deeming any languages as safe. But they are recognizing some languages as safer than others. Safety isn’t a binary switch, and most people recognize that. Most people also recognize that using tools that make it harder to achieve safety, does, in fact, make it harder to achieve safety. And thus, if safety is important, avoiding those tools makes perfect sense.
