Nothing to add to the list? Nada?
Your title asks for defenders of Materialism and yet your post asks for us to refute your version of Idealism.
Your assumption, then, is that there are only two metaphysical systems that have been proposed, but there are not.
So you need to clarify which you want.
The next problem is that I can hardly refute a claim that I haven't seen. Giving us a link to a general website does not help - exactly what part of that website do you want us to address? There are different flavours of Idealism, we need to know which one in particular.
So if you could give a link to a statement of your metaphysical claim then at least we have something to address.
Too often here we find someone claiming that everything is consciousness and when we probe we find that they mean that there is some consciousness that is not currently conscious. So, in other words, they are claiming Materialism with some of the labels changed.
Are you proposing a Theistic version of Idealism, as Berkeley proposed, with one mind which controls the perceptions and keeps them consistent?
Or are you proposing a subjective Idealism such as Erwin Schrodinger believed?
So, if you are asking us to refute something, give us a link to the claim itself. But if you give us a link to an entire book then I am afraid that my backlog of reading will not permit me to to get to it for some time.
Perhaps you could give us the gist of it, something more definite than you have in the OP but short enough for us to read in a realistic time.
