Why do Kikuyu women find it so easy to disrespect Kikuyu men?

If there's a community where women comfortably undermine their men, it's the Kikuyu. Thanks to my insomnia, I've decided to download X and I came across this post that is technically promoting paternal fraud. The reason, allergy. Apparently Kikuyu men are carriers of genes that bring forth short children and protein allergies so Kikuyu women are allowed to procreate with men from other tribes while married to their men. Ridiculous, right? Is it that Samburu or other communities don't get allergies or asthma? I now understand why other people find it so easy to slander men from my community.

It's also interesting to see how most of these people are quick to condemn cultural aspects they consider bad or harmful like polygamy but will promote any other aspect that seems to favour them. I'm wondering when the rains start beating Kikuyu men. Personally, I was raised in a home with a strong father figure before his demise and I inherited his calmness and self control. I never came across such thoughts even from my mother who even decides to remain unmarried after my father's death. That's beside the point though. I've never come across women from other communities openly undermining their men. I mean, if you love me from a certain community why not get married there instead of marrying a fellow Kikuyu man then going to get impregnated by a man from another community? So women were allowed to get impregnated by men from other communities but somehow men weren't allowed to get women from other communities pregnant in a patrileneal society? The funny part is that what she's saying is untrue.

Kikuyu guys, I hope you are living beyond the stereotypes out there.
