Well that seems rather petty.
What about fruit? An apple, an orange and a pear are all different but at the same time all fruit. By the mathematical proof they couldn't be different and yet the same thing, but they are... the key thing being we aren't talking about the same attribute... Father/ Son/ Spirit = person. God = essence.
