I too have noticed the preponderance of "woo", pseudo-science and anti-vax on Steemit, it's a bit disheartening BUT they are not the only people here and in the end science doesn't care what you believe it just works.

Now the thing is to use science (as in the scientific method of experimentation etc) to find an effective way to change and enlighten minds.

I'm with you! RESTEEMED, voted and followed!
