While making your point you did manage to insult some of us, some of us may be sensitive to our gender information being known, and some of us may be sensitive to humorous "unintentional" insults being used to make a point. Is your point that gender never matters in a reading situation or that you are personally bothered by any reader asking your gender up front before a reading takes place?
This is a Pet Peeves thread, which is essentially a vent thread, so I would suggest if readers don't want to read about what annoys some of us or might be offended don't come here again. Personally I find the information in this thread to be informative and useful even if it does poke at some things I may or may not be guilty of ;-) Yes, it is a Pet Peeve of mine that people mandate gender/age for readings because I am sensitive that this is an anonymous username website and as such some people don't want to disclose anything beyond their username. Also, I don't think this information is necessary to read the cards effectively. Lastly, I think this information feeds into a readers biases and may not even be as useful to them as they think.
