That’s not a nice thing to say. I bet they —and everyone— could learn from getting some of the myths dispelled, instead of just getting insulted.
I don’t have time to write all of that out. Start over without any of these guesses as to what these materials do. It’s irresponsible to say things as if they’re facts, when you know nothing of the subject. Like your most recent post.
You wrote a decent response a few comments down, that’s good enough. This isn’t ExpertSexChange, so some people might not be experts, but I think we can collectively manage the basic stuff while treating everyone with respect. As for my most recent post, I’ll admit having sent it before fully reading their sources, but probably should discuss it over there if you want?
