Calling nonsense "nonsense" is not an insult unless you believe in said nonsense. No religious person would find the statement "belief in Thor is nonsense" objectionable or offensive at all. In fact, most would agree without reservations.

You also missed my point about taking a scientific approach to something like ebola. Gas masks are utterly irrelevant and pointeless. We know how the virus is spread and we know that if caught reasonably early it is easy to kill. Even if your entire neighborhood consists of people with ebola you and your children are safe as long as you don't swap bodily fluids. I don't know about you, I can't remember the last time I swapped bodily fluids with my neighbors. So, yeah, others can pray --which is utter nonsense-- I'll stick with scientific knowlege --which is not.

Here's the difference with science: If tomorrow someone offered true evidence that ebola is now airborne and prayer kills it, I could not imagine a single scientist who, when presented with the evidence, would not accept these findings to have a high degree of probability of being true.
