"Safe-spaces" are practical application of the principle, accidentally unearthed by xyz-equality movements of the 20th century, that people generally don't like hurting others and hence you can control them by appearing to be hurt, whether you are or not.
People modeling victim behaviors to remove everything that causes them discomfort aren't something to be afraid of, but also their cries for attention aren't something to be treated too seriously. Allowing them to get their way just reinforces further learning of this silly strategy.
