It can be infectious. You can catch the disease and not even know it as a carrier with outward, but not inward symptoms, or any way you want to look at it. Alanzo caught the disease as well and attempted to pass it on.While OSA types might well do that, quite a large number of posters on Rinder's and Tony's blog make hyperbolic statements and I'm pretty sure they're not agents. It is understandable that people are upset about the bad things done.
Sorry to agree with Alanzo, but it goes over the top way too much and makes those against scientology abuses look like fanatics.
