For the purpose of this move I've divided this season's male species we know as Manono into three groups.The first group involved the ones spearheading this move. Yes they are morons but to insinuate Colton and Greg and samples of the general population of the male species is insulting.
The second group who were totally on board with the idea possess as much backbone as a jellyfish. I would label them more embarassing than dumb.
And the last group were not thrilled about the whole move but when it's tribe vs. tribe majority will rule within a tribe. They were more victims of circumstance in my opinion.
My final decision on how dumb any move is will depend on the aftermath or effect of such a move. Potentially this could be the dumbest move ever, but Colby and Lil's moves proved to be $900,000 blunders! That's a lot of Do-Re-Mi, so the after effect of Manono's decision to go to TC would have to yield some monsterous and tragic repercussions for me to personally replace Colby and Lil's decisions as the "dumbest move ever."
