I realize this might be a contentious question, but this seemed like the right place to ask. Please redirect me if not.
The background is that I am a "practitioner" (PhD student, I don't study CS theory) but I have a reasonable foundation in undergraduate algorithms and math. Nevertheless, discussions with theorists are usually very surface-level, as if they're afraid to use mathematical terms with me in case I get scared. In reality, I'm perfectly comfortable with and interested in theory, but I'm just not used to discussing it so I probably don't always use terms that would flag me as "theorist". I find that the direct approach ("please tell me the details") doesn't always work, particularly if the theorist in question has assumed a condescending tone that sets a high bar for expertise (this happens often).
As theorists, if you filter people in this way, do you have recommendations for how a practitioner can avoid being "flagged" by your filter?
