I'm going to remain anonymous so it's unbiased.
A&B are teenagers (one is 18, other is slightly younger), they're in a relationship. Today, they went to a house of relative for person A, other family members were there aswell including person A’s parents.
A&B were being touchy (as I suppose teenagers are), one of them then sat on the others lap, briefly.
Person C, told them to keep their hands to themselves and to stop being so touchy infront of everyone as no one wants to see that or know about their sex life. Person D (one of person A’s parents) thought person C was BU, and accused them of being homophobic as they thought person A&B weren't doing anything wrong, Person C didn't stand down and was adamant person A&B were in the wrong, and they weren't being homophobic.
Who was in the wrong?
