"It is comical that they think their word matters" - From that site's contact form.
Such a disparaging and dismissive comment before you have even aired your views! It is quite clear that the author(s) of that site have no interest in honest debate about a subject that has to be debated. So therefore, what is the point of wasting valuable time with such a cretinous individual(s).
It should also be quite clear that their site is full of copy and paste assertions rather than reasoned arguments based on given evidence.
And finally, just look at the comments left by the apparent owner of that site. That should tell you the education level of the authors of that site.
