It doesn't help that this sort of male looks upon women the exact same way they look at a car or a boat: something to have. Even the Columbine killers had the same attitude in their journals ("Can't get girls.") And notice, it's "girls" plural. Like one would not be enough, one must have access to a harem.
This very attitude gives off a scent that scares women away, so frankly, beta males are alone because they deserve to be alone. It's a nasty personality type. No surprise they gravitate to Islam or some other extreme ideology that promises to give them the status (and assets) they think they deserve.
You are describing an "omega male" type.
The classes of males, in the Alpha/beta/etc hierarchy is:
Alpha: a man who attractive women would be interested in having sex with, EVEN if he displays no interest in marrying them or is otherwise unlikely to go into a long-term committed relationship (although many women with excessive self-esteem may delude themselves into thinking that SHE will be the one to finally nail him down). Represents 10 percent or less of the male population.
Beta: a man who a woman would ONLY sleep with because he might marry, or otherwise commit to her, and offer some degree of financial security. Represents about 70-80% of the male population.
Omega male: a male who most women are uninterested in sleeping with. Will only get sex from hookers, or desperate omega females.
