Even if that is true... so what? And, of course, he did not "discover" North America, since there were already people here.
I've posted this theory on another thread, but I think it bears repeating...
This is DOC's MO. In his Jefferson and "Peter in Rome" thread, he posted a point that was minor and, even if true, didn't mean anything. All direct questions asking him what his point was for raising these issues were usually ignored or simply would accuse the questioner of personal attacks.
I am left to assume(since he refuses to say it) his point is to "prove" that christianity is great and wonderful and is the only thing that is worthwhile because
1.) Peter was in Rome
2.) Jefferson was devoutly religious
3.) Communism would have succeeded if it was christian
4.) only christianity can rescue someone from drugs
5.) Secular humanism is a religion
6.) ACLU hates christianity
7.) Leif Errickson is a christian
Unfortunately, all of these claims are "not even wrong".
However, this fact doesn't seem to matter to him.
It is the quantity of arguments rather than the quality of the arguments that he is going for. Eventually, I expect him to post something along the lines of, "How can you continue to deny? Look at all of these points, christianity must be valid..." It is with the hope that at this point that all contrary arguments will sound like the ones coming from a petulant child.
I could be wrong, but we'll see. In any case, such strategy is only effective in debate theater. On this internet, which can be read at leisure, truth wins out.
