There is an interesting paper published in  Evolution & Human Behavior on the effects of religion on men and women. The paper is entitled “Religious cognition down-regulates sexually selected, characteristically male behaviors in men, but not in women” and was written by Michael E. McCullough, Evan C. Carter, C. Nathan DeWall, Carolina M. Corrales.

Abstract: “Men are typically stronger, riskier, “showier,” and more impulsive than women. According to sexual selection theory, such behaviors may have enhanced reproductive fitness for ancestral human males. However, such behaviors are facultative, and the mechanisms that cause them respond to social and environmental cues that indicate whether outlays of strength, risk-taking, showing off, or impulsivity are likely to lead to payoffs in any given instance. Recent research based on the Reproductive Religiosity Model suggests that, in contemporary Western societies, religious beliefs and institutions are differentially espoused and promulgated by restricted sexual strategists (whose reproductive strategies focus on high fertility, monogamy, and high parental care) to limit the exercise of unrestricted sexuality, which threatens the viability of restricted sexual strategies (e.g., by reducing paternity certainty and male parental investment). On this basis, we hypothesized that experimental manipulations of religious cognition would reduce men’s impulsivity and motivation to demonstrate their physical prowess. Supporting this hypothesis, three experiments revealed that priming participants with religious concepts (i.e., participants wrote essays about religion, read an essay supporting the existence of an afterlife, or were implicitly exposed to religious words) reduced men’s (but not women’s) impulsivity with money and their physical endurance on a hand grip task. The primes affected men’s behaviors irrespectively of men’s scores on a self-report measure of religious commitment.”

Well, it might hurt the feelings of some good men, but it seems that religion reduces men’s “physical endurance on a hand grip task” and in general make men less masculine. From the manosphere perspective, the evidence suggests that religion acts to betazied the male population and control men’s sexuality. In the past, religions also limited women’s sexuality and increased paternal certainty, thus making this a reasonable contract. In the present, since the social contracts are broken (even for the religious)  it is against the self interest of men to remain religious.  Slut is the default mode of the western woman. Sluts go for alphas. Hedonistic behavior (i.e. follow your heart bs…) will always lead women to alphas. Since religion enforce betazation of men under the current cultural climate it makes no sense for men to be religious.
