Care to specify exactly what in the design among the sexes you consider incompetent, brain dead and cruel.
Sure. There are a lot. But just for starters -
Women are "designed" to give birth through their vagina. Being that humans have large brains and the vagina goes through the pelvic girdle, which isn't big enough for a good sized brain, this is a stupid design. Even more stupid are the "fixes" put in place - make females less able to walk by having a bigger pelvic opening, babies born prematurely, etc. A non-stupid design would be to simply have a "C-section" opening in the belly for birth.

Next - women are "designed" to have added fat under the breasts, to make the breasts look more developed. Men are "designed" to lust for larger breasts so as to ensure maturity. Why would a God simulataneously design this system of lust and then condemn lust?

Third - Men are "designed" to have frequent sex with multiple partners. We can see this by ball size. By contrast, gorillas are completely free of vaginal sperm competition - where women have sex often enough with different partners for sperm from different males to be present at the same time - and hence, they have testicles the size of beans. Larger testicles are only useful if one is having sex with women who have recently had sex with other males. Only an insane, incompetent, or cruel God would design men for adultery and the condemn adultery. http://www.sapiens.org/blog/animalia/sperm-competition-ball-size/
All of these problems and more are solved by theistic evolution. By freeing God from the idea of micromanaging the many designs, we theistic evolution supports no longer have to blame God for the many evil, incompetent, or cruel designs in the real world.
Also what does the following have to do with it?
But whoever blasphemes against the Holy Spirit will never be forgiven; he is guilty of eternal sin."
The holy spirit is part of the Godhead, as per the trinity. If one is a supporter of the idea of the trinity, then blaspheming the designer is blaspheming the holy spirit. Denying evolution blames the designer for the many stupid, incompetent or cruel designed that biologists agree are clear in the real world. Thus, the only escape from the Gospel command to not blaspheme God is to support theistic evolution.
