Sounds like a mod. The only blade fugitives in Skyrim by default are Esbern and Delphine.(Both of which are permanently essential and unkillable)
There actually is a drunk at the Nightgate Inn who's rumored to be a former Blades agent - I haven't investigated it myself though (console here, no mods).
The rest sounds weird though. I mean, that's a common complaint, that there's so much talk about racism, hatred between the races and so on, but when it comes to the PC, apart from a few greetings no one seems to care.
