Spoke to a stranger and regretted it. AITAH?

I saw a guy wearing an EXTREMELY niche Christian band Tshirt (a small band from our town almost 20 years ago) at my local gym. I knew this band back in the day so I went over and said as much. We chatted for a little while and while it was strange in parts (the guy asked me if I had any evil tattoos and which church I attended) it was relatively pleasant enough. We shook hands and I went back to my workout.

He then walked across the gym floor and had me take out my AirPods to tell me about another band I might like. I smiled politely and said something along the lines of “cool, I’ll check them out”.

I made my way to the treadmill and began my run. He again finds me and this time taps my hand. I stop running to hear him and he then gives me a lists of churches I should try. At this point I rudely respond to him that I’m not interested in his suggestions and I really just want to finish my workout. He turns in a huff and walks away.

Now, whenever I see him at the gym, he death stares me as if I’m just a huge AH. Is he right? AITAH?
