Is it okay? Yes
How do I feel about it? It's off putting. I feel like as parents we sometimes have to use our better judgement and separate what's best for us, from what's best for our kids. This was for him and his lover with no regard for the light the kids will now stand in. Two white dads with black sons who are encouraging them to kiss is not going to go well on social media. You have to know this as an adult with common sense. So the only reason for posting this IMO is to make a social statement or low key bait for a reaction (because you know you're getting one). If it was merely about love you would have enjoyed your private moment, and be content with not subjecting your children to public shaming on social media. What ever positive feedback or new normal dad of the year award he received isn't worth the spotlight that is now place on his kids and family. The trade off isn't worth it and I would protect my kids from social media trolls.
