This is basically a semantic debate, but I guess this all is anyway. I don't disagree with the pattern you are describing, but I would describe it a slightly different way. There are people getting offended on the behalf of other people who potentially might get offended. Even if this second group never materializes or doesn't even exist, that first group is still getting offended on their behalf.

Basically I don't believe that "precaution" you mention is an apathetic but cautious person. These changes are more often motivated by someone who thinks "this might offend someone so I will take offense to it too".
