She may be a lez; more likely, though, she has a quear son or something (not trying to start a rumor; but mothers of mohos tend to develop empathy — Stockholm Syndrome dontcha know).
It is not only the mothers of homos but they influence their entire extended families. Think how many people that can be; brothers and sisters, moms and dads, grandmothers and grandfathers, aunts and uncles, first and second cousins and nieces and nephews. Then the homo’s extended family is connected by marriage to other families who also have their extended families. So think what a sphere of influence they have and think how they must divide families when they decide to “come out of the closet”. If the gay wants to come over for Thanksgiving dinner, Christmas, barbeque then those that don’t agree with that lifestyle will be forced out of the family event. And what happens when they want to bring along their “significant other”? People who are offended just have to keep their mouths shut to keep the family peace and what about explaining all this to kids.
