It becomes (or at least implies) too much anecdotal, which is not ideal for a unopinonated discussion.

Excessive use of first person imo is a good flag that the writer is too self concerned (egotistical), which can interfere with their judgement (as it’s affected by ego and not a cold, rational look at both sides). Which I’m guilty of from time to time.

I realized that as I was halfway through, but it was too late in the night so I just pressed reply :)
