I didn't insist on anything in the first place. I merely didn't see anything objectionable about calling the Big Bang the "Big Bang Theory".
I don't have any objection to your calling creationism "Creationism Theory", either.
But, of course, the unspoken debate here is how these things are referred to in schools, where the Big Bang is freely discussed, and any mention of creationism is prohibited.
Ah -- then perhaps we didn't communicate clearly to you that the issue we're discussing is not "calling it the Big Bang Theory" but instead "insisting it always be referred to exclusively as 'The Big Bang Theory'".
So maybe we don't disagree at all, and somehow didn't clearly explain what our objections to his behavior were.
