Fluffy posts, like stated above, are un-true and usually go to claim that they will turn you into a vampire/ werewolf/ mermaid, or claim to do rediculous things. You can tell if a post is 'fluffy' by using common sense.
Magic is science, just because science is shedding more and more scientific light on our craft and explaining it on their terms does not mean magic itself is changing. Magic, while there definitely have been new growths and innovations, has been practised for quite some time, and despite finally starting to be scientifically explained, does not change the practise itself.
Science has changed it's views on magic, an has certainly enlightened practitioners who read up on it, and has given us a deeper understanding of our own craft, science has changed nothing about magic, only our views of it.
