Am I being a judgmental atheist or is this pastor an asshole

I have no problem with religious people, my dad was a pastor, I grew up in the church. Just realized it's not for me. My brother goes to church and follows his pastor on Instagram and was showing me these funny comments his pastor leaves under atheist pages. He was showing these to me and honestly I think this guy is a dick! My dad who was a pastor and goes to church every Sunday even said "No. That guy is awful." So I want opinions. Example of some of these "funny" comments he leaves that my brother finds hilarious. Someone was saying on some post that is God was real then why does he let school shootings happen? My dad would have a completely different response than this fucking guy. I guess he went on her page to find stuff out about her and commented "The fact that he let your ugly ass have 4 kids is proof their is a God." My brother thinks it's hilarious. Am I missing the punchline? How is that appropriate for someone to say? Another one my brother showed me was under a picture where there was a line between church and state and this pastor comments "Spoken like a clear power bottom." My brother thinks this pastor is hilarious and I'm just like "Wtf is wrong with you?" He talks like this all the time and even posts his comments on his page. I think someone needs to take this guys Internet away because I'm sorry he sounds like a middle school boy on a troll account. Am I being judgemental or is this guy a dick?
