Sisko is awesome. He’s a quiet, one man 24th Century equal access revolution. He’s the Captain who:

• Wrote a letter of recommendation to allow the first (and only) Ferengi to join Starfleet
• Had the first (and only) Klingon in Starfleet as his Commander. AT THE TIME that it seemed very likely the Federation and the Klingons were about to go to war.
• Pulled strings to keep the first (and only) openly Augmented Officer in Starfleet from losing his commission and kept him on as his Doctor even though he was illegal. ALL WHILE never once mentioning that Bashir had lied to him for five years.
• Had the only Changeling in the quadrant as his Chief of Security. AT THE SAME TIME as there was a mass-panic about Changelings and the Federation were at war with them. AND never once suggested Odo try and become more humanoid…

Half of his senior staff are exceptions. He supports them quietly and, presumably, behind the scenes defends their right to be there, mostly without them knowing it. Sisko rocks.
