Do you get raped by the Flying Spaghetti Monster and his gang of pirates? Discuss.
If not, then there's no reason to not believe in it, (assuming that elective belief is a thing).
In fact, it's probably one of the ugliest theories to be particularly invested in to begin with, with one's level of enthusiasm for evolutionary theory often being "inversely" proportional to their actual mating success, making one even wonder if it would better to "not" believe in it than to do so, as superstitious as the notion of "believing" in any body of theory or abstraction is to begin with.
I'd much rather study music theory, than evolutionary theory, to be honest, even as a scientific theory, it's entirely overrated, physics being much more fundamental than biology, and a hell of a lot cooler (in physics, you get to learn about black holes, in evolution you get to learn about cows humping each other).
And it seems to be common knowledge that musicians, whether Bach or Rock tend to do a lot more actual sexual reproduction than the average, overweight, white, male evolution fetishist on the internet does, likely having more in common with the mating and hygiene habits of a lesser ape than the average non-socially maladjusted person does, and much like an animal, likely isn't able to tell the difference between a Waifu and and actual woman, other than maybe when she pulls out the pepper spray - which a Waifu, of course can't do.
Hehehe
Evolution? My ass. More like devolution? Science? Nah, more like a failed HS science experiment come to life.
I don't think this strapping young fellow is particularly concerned about regurgitating ugly, banal factoids about evolution, and if anything he and his lovers are evolutionarily speaking, the better for it. Seems to work in reverse - the less you know about evolution, the more actual evolution you and the ladies end up doing. Mhmm.
Pathetic.
