You're scolding this person for their impassioned comment but should also maybe self-reflect a bit. Maybe this person is upset because you're casually throwing out baseless, unsubstantiated claims.
If you want to have a constructive conversation about real life events, you may want to have more evidence for your claims than "I’m more inclined to believe" and "There likely was..."
I’m scolding them for using profanity in the first word of their first sentence. There is no way to have a constructive dialogue with someone when they show that much anger off the bat. That sort of hostility just breeds more venom which won’t lead anywhere productive. If we’re just hear to air our grievances. Then it’s fine, be angry, show that emotion. Feats of strength are next. Someone can bring out the festivus pole.
But I don’t think that’s what this forum is about. If his problem really is my lack of evidence he should say that instead of spewing obscenities.
