Keep in mind that in LDS young single adult culture, returned missionaries are encouraged to date a lot of different women as part of the process for finding a spouse (and vice-versa). Women get asked out a lot and are probably more open to dating someone they're not necessarily super attracted to because it's not a commitment for sex, it's simply a social activity.
So there is more frequently tolerance for "that guy" that is kind of obnoxious about it as long as he's not hounding the same female (which we know that he eventually did).
Also people are going to try to be as charitable as possible for someone who has some obvious limitations because they're trying not to be cruel. My biased opinion is that a lot of LDS people are extremely accommodating because they're genuinely trying to apply their religious principles. Of course this leaves the door open to people who will take advantage of that nature and there are more than a few examples of LDS conmen like
Trevor Milton.
It's a difficult thing to navigate when your organization is tasked with both the temporal and spiritual welfare of its membership.
