It is a good idea to ware safety glasses. Even tho it is unlikely a primer will even go bang does not mean you should tell someone to disregard common safety equipment that should be used when doing any reloading.
I can't say you're wrong, but I tend to agree with jcwit. It's just not that dangerous. The downside to saying one needs faceshields, glasses & a hazmat suit is that it could change the perceptions to the point that all of a sudden we can't reload anymore because the nanny state says it's too dangerous.
By all means, be safe and practice reasonable safety precautions, but let's keep it in perspective, shall we?
