"Real alphas don't care about their wives' s8xual history" is quite a novel take from VD.
There are 2 things which come to mind. From a purely pragmatical point of view, most men and women nowadays, outside of strict religious communities, will marry someone with a s8xual history, it's just a fact of life.
On the other hand, the idea that "the real Alpha male", (such as presumably D. Trump) wouldn't/shouldn't care even if he marries a total wh8re is, frankly, ridiculous and could only appear in our deprived society where "hotness" is the highest value and virtue is despised.
It also says something about the character of the person who espouses this point of view. Notice the mockery of "trad" girls and the idea that men who don't want to marry promiscuous women are insecure.
