Don't mean to mean obnoxious, or personal for that matter, but, why is this still a thing?
We have people in every level of public office and in every professional industry with the most interesting names from various religions and localities.
Why do we (as Jews) feel that if we put our real names on our legal documents, we'll be discriminated against?
Discrimination isn't the only reason. IINM, and there are others on this forum who can correct me if I'm misstating it, there are those who b'shita use secular names at work so as to separate their work life from their home life.
Personally, I use my name at work, except when I'm calling a customer service rep or the like who I will never speak to again. My name isn't tough to pronounce - it's an English word - but it's an unusual name, so I don't want to waste the time it inevitably takes on the back and forth with the rep with them confirming they got it right. If I had a Ch in my name I'd definitely be annoyed using it all the time.
It's traditional. For centuries (1200-1500?) most men had two or more names, one based on the local language that was used everyday (like Leib) and a Hebrew shem kodesh (like Yehuda) used on religious occasions and documents. At some point (1500-1600s) it became common to combine these as a single shem kodesh (Yehuda Leib), but we certainly have a long tradition of using separate names for different purposes.
And then came the 2000s, when we went back to using Leib for everyday, and Yehuda for online forums.
