We are not threatening you. On the contrary, we want our girls to be happy with any character, be it canon or oc., be it male or female.
Maybe because that man looks like a rival to them – or it could be something out of evolution/innate psychology that makes living beings compete against rivals.

Nor do they get angry at lesbian relationships between the girls themselves… Ah, but when a girl is with a canon man, they get angry and make war. That is why the brony fandom is in decline.
