""Then they go on to explain their reasons and supply evidence for their viewpoint""

Oh, the old "where is your evidence" question that some frequently "spew off" in the religious posts. IMO, that's a surefire discussion ender, with zero resullts for everyone.

When someone has a viewpoint, it does not mean they have scientific evidence for that viewpoint. It can be like asking what evidence do you have that blue (which you prefer) is better than yellow (which you may not like). IMO, that condensending type of questioning is like not-so-stealthly saying ""That's the stupidest thing I've ever heard!!!!!!!!! Where the hell did you pick up that wad of bullshit""
