“What’s the problem?”
He’s picking on the child over something the child can’t control.
Not really true. If the child goes to authorities and complains of abuse, he can be put in foster care. Who wants to grow up with perverts? Watching the activities and listening to the conversations has to be considered abuse. Sodomy has been an abomination since Sodom and Gomorrah. As you watch the natural progression of the acceptance of perversion, we see men being changed into women, and men allowed in women's bathrooms. People are now trying to marry robots and animals. California now recognizes 3 genders.
How far are you willing to go down the sewer trying to convince yourself these people are normal and to be allowed around your children? It was obvious to any thinking person why homosexuals wanted to be scout masters. Look at it now. If you would be appalled at me, a 66 yo male, to be a soccer coach for female teens in the dressing room, why would you accept a lesbian woman watching your daughter shower?
This is not going to end well. It can't help but get uglier and uglier. The Bible says the Land is defiled and will vomit you out if we allow this in our country. Are you smarter than God? Or are we making the same mistake over and over since Eve ate the fruit? I choose God even if I'm the last one.
