How do I exactly lose credibility for pointing out what happened?
Because Dany doesn't allow shit. The Dothraki are a race of pillagers, rapist, and murders. Drogo has hundred of bells in his hair, meaning he's won hundreds of battles. He raped, pillaged and sold slaves long before Dany. All Dany supplied was a direction for what to do with the money they got. Blaming Dany for Drogo's actions is about as straw man as you can get.
Is she dishonorable? Maybe, but who isn't? It's just the world they live in and the definition of Honor they use. Cheating the Slave Masters, dishonorable? Maybe, but don't expect me to cry over men who cost millions of lives. Someone once broke down the "cost" of each unsullied, for 1 unsullied soldier something like 10 people die. I'm not shedding tears over ending that practice.
The 2 worst things Dany has done IMO are allowing the wine sellers daughters to be tortured and leaving Astapor with no real government. One was done out of desperation, one out of naiveté.
