I guess "safe space" (quoted as a term under discussion) isn't really the right term here - but the student is the one who raised the issue of "victimization", which to my mind is really more what we're talking about than actual safe spaces as you defined them. So on this point, that might actually be good feedback to that professor, because I think struggling with the terminology in this particular topic is common.

One thing to realize ...is the context of love ...in many evangelical circles

As a conservative evangelical myself, your explanation of the Christian concept of love is somewhat confusing and contradictory to me. But putting that aside, I still don't see how this student felt "victimized", unless now any negative feeling or emotion makes one a victim. Feeling guilty for failing to live up to a standard is a negative feeling, but I don't think it makes one a victim (and if it does, then I think the word victim becomes utterly void of meaning).
