I met someone with a stutter and wanted to say "me too, brother" and fist bump him but I chickened out

I met someone with a stutter and wanted to say "me too, brother" and fist bump him but I chickened out I thought he would be embarrassed so I didn't say anything. But I don't know if I did the right thing. Maybe it would have been cool to bond, but I didn't want to point it out because maybe he hoped I didn't notice? Have any of you ever bonded with a stranger over stuttering, or is that inappropriate because of how emotionally charged it is?
