Therefore, since most mutation is harmful, the line would DIE OUT instead of INCREASING; if the ToE is true.
No, it wouldn't. Go learn something about population genetics before you spout any more ignorant nonsense. Selection causes beneficial mutations to increase in the population, and negative mutations (such as this one) to eventually be weeded out. This has been confirmed in thousands of different field, lab, and theoretical studies. So your derision is not only misplaced, it's embarassingly uninformed. If you're trying to help reinforce negative stereotypes of conservatives, you're doing a great job.
But it's not an instantaneous process, and harmful mutations will usually persist for a number of generations before being flushed out of the genepool, as is happening in this case.
