No surprise. Try arguing with most leftists, they cannot defend their positions (and either resort to silencing critics or insults). I don’t know what sect he’s in, but if it still has even an ounce of Christianity left to it, I’d contact his higher-ups and report his blatant anti-Christian activities. People get canned over social media posts, and he should be no different.
Good suggestion. I talked to my son and we are going to research a complaint. It is a huge church. We have been splitting time with our adult kids going to the churches they have chosen, but I told my son i didn’t intend to go back to his church.
